Support only VM pointers and ref-counting for maintaining VMs. This
dramatically reduces the complexity of the APIs, avoids the API
abuse that has existed, and ensures that future VM usage is
consistent with current usage.
Also remove the combined VM free/instance block deletion. Any place
where this was done is now replaced with an explict free of the
instance block and a nvgpu_vm_put().

Since all debugfs code is Linux specific, remove
it from common code and move it to Linux module
Debugfs code is now divided into below
module specific files :
common/linux/debug.c
common/linux/debug_cde.c
common/linux/debug_ce.c
common/linux/debug_fifo.c
common/linux/debug_gr.c
common/linux/debug_mm.c
common/linux/debug_allocator.c
common/linux/debug_kmem.c
common/linux/debug_pmu.c
common/linux/debug_sched.c
Add corresponding header files for above modules too
And compile all of above files only if CONFIG_DEBUG_FS is set
Some more details of the changes made
- Move and rename gk20a/debug_gk20a.c to common/linux/debug.c
- Move and rename gk20a/debug_gk20a.h to include/nvgpu/debug.h
- Remove gm20b/debug_gm20b.c and gm20b/debug_gm20b.h and call
gk20a_init_debug_ops() directly from gm20b_init_hal()
- Update all debug APIs to receive struct gk20a as parameter
instead of receiving struct device pointer
- Update API gk20a_dmabuf_get_state() to receive struct gk20a
pointer instead of struct device
- Include <nvgpu/debug.h> explicitly in all files where debug
operations are used
- Remove "gk20a/platform_gk20a.h" include from HAL files
which no longer need this include
- Add new API gk20a_debug_deinit() to deinitialize debugfs
and call it from gk20a_remove()
- Move API gk20a_debug_dump_all_channel_status_ramfc() to
gk20a/fifo_gk20a.c

nvgpu_log/info/warn/err() internally add a \n to the end of the message.
Hence, callers should not include a \n at the end of the message. Doing
so results in duplicate \n being printed, which ends up creating empty
log messages. Remove the duplicate \n from all err/warn messages.

Put all debugfs dependencies inside #ifdef CONFIG_DEBUG_FS. This
includes some functions in allocators that were used only for
debugging.
Remove include of linux/debugfs.h on files that do not deal with
debugfs.
linux/debugfs.h implicitly included linux/fs.h, which we relied on.
Add explicit include of linux/fs.h for all files where this is the
case.

Don't use enum dma_attr in the gk20a_gmmu_alloc_attr* functions, but
define nvgpu-internal flags for no kernel mapping, force contiguous, and
read only modes. Store the flags in the allocated struct mem_desc and
only use gk20a_gmmu_free, remove gk20a_gmmu_free_attr. This helps in OS
abstraction. Rename the notion of attr to flags.
Add implicit NVGPU_DMA_NO_KERNEL_MAPPING to all vidmem buffers
allocated via gk20a_gmmu_alloc_vid for consistency.
Fix a bug in gk20a_gmmu_alloc_map_attr that dropped the attr
parameter accidentally.

Move clock APIs from gk20a_platform to gpu_ops. At the same time
allow use of internal get_rate/set_rate for querying both GPCCLK
and PWRCLK on iGPU.
At the same time we can replace calls to clk framework with the
new HAL and drop direct dependency to clk framework.
gp10b ops were replaced as a whole at HAL initialization. That
replaces anything set in platform probe stage, so reduce that to
touch only clock gating regs.

1) Trace buffer allocation now calls generic gmmu alloc/map.
so for dGPUs they are allocated in vidmem and iGPUs they
are allocated in sysmem
2) Use pmu surface mechanism to setup trace buffer params as
dGPU binaries follow falcon memory structure to get mem surface
params
3) Fix minor coverity issue by removing unnecessary overwrite
of count variable in trace print function

Instead of using Linux APIs for mutex and spinlocks
directly, use new APIs defined in <nvgpu/lock.h>
Replace Linux specific mutex/spinlock declaration,
init, lock, unlock APIs with new APIs
e.g
struct mutex is replaced by struct nvgpu_mutex and
mutex_lock() is replaced by nvgpu_mutex_acquire()
And also include <nvgpu/lock.h> instead of including
<linux/mutex.h> and <linux/spinlock.h>
Add explicit nvgpu/lock.h includes to below
files to fix complilation failures.

Move semaphore_gk20a.c drivers/gpu/nvgpu/common/ since the semaphore
code is common to all chips.
Move the semaphore_gk20a.h header file to drivers/gpu/nvgpu/include/nvgpu
and rename it to semaphore.h. Also update all places where the header
is inluced to use the new path.
This revealed an odd location for the enum gk20a_mem_rw_flag. This should
be in the mm headers. As a result many places that did not need anything
semaphore related had to include the semaphore header file. Fixing this
oddity allowed the semaphore include to be removed from many C files that
did not need it.

Remove including gk20a.h from pmu_gk20a.h. This causes a fallout
as some #includes were missing.
gr_gp10b.h uses mem_desc, but did not include mm_gk20a.h. Add the
include.
Including mm_gk20a.h in gr_gp10b.h causes recursive include, as
mm_gk20a.h has some gr defines. Move the defines to gr_gk20a.h to
remove the dependency.
gr_ctx_gk20a.h used struct gk20a pointers, but did not forward
declare it. Add a forward declaration.
gr_gk20a.h uses dbg_session_gk20a, but was missing forward
declaration.
gr_gk20a.h did not include nvgpu.h but it uses preemption types from
that header. Add include.

Reorganize the HW headers of gk20a. The headers are moved to a
new directory:
include/nvgpu/hw/gk20a
And from the code are included like so:
#include <nvgpu/hw/gk20a/hw_pwr_gk20a.h>
This is the first step in reorganizing all of the HW headers for
gm20b, gm206, etc. This is part of a larger effort to re-structure
and make the driver more readable and scalable.
