Create an nvgpu internal nvgpu_gr_sm_error_state to store and
propagate SM error state within driver. Use
nvgpu_dbg_gpu_sm_error_state_record only in Linux code.

Move vm_priv.h to <nvgpu/linux/vm.h> and rename nvgpu_vm_map()
to nvgpu_vm_map_linux(). Also remove a redundant unmap function
from the unmap path. These changes are the beginning of reworking
the nvgpu Linux mapping and unmapping code.
The rest of this patch is just the necessary changes to use the
new map function naming and the new path to the Linux vm header.
Patch Series Goal
-----------------
There's two major goals for this patch series. Note that these
goals are not achieved in this patch. There will be subsequent
patches.
1. Remove all last vestiges of Linux code from common/mm/vm.c
2. Implement map caching in the common/mm/vm.c code
To accomplish this firstly the VM mapping code needs to have the
struct nvgpu_mapped_buf data struct be completely Linux free. That
means implementing an abstraction for this to hold the Linux stuff
that mapped buffers carry about (SGT, dma_buf). This is why the
vm_priv.h code has been moved: it will need to be included by the
<nvgpu/vm.h> header so that the OS specific struct can be pulled
into struct nvgpu_mapped_buf.
Next renaming the nvgpu_vm_map() to nvgpu_vm_map_linux() is in
preparation for adding a new nvgpu_vm_map() that handles the
map caching with nvgpu_mapped_buf. The mapping code is fairly
straight forward: nvgpu_vm_map does OS generic stuff; each OS
then calls this function from an nvgpu_vm_map_<OS>() or the like
that does any OS specific adjustments/management.
Freeing buffers is much more tricky however. The maps are all
reference counted since userspace does not track buffers and
expects us to handle this instead. Ugh! Since there's ref-counts
the free code will require a callback into the OS specific code
since the OS specific code cannot free a buffer directly. THis
make's the path for freeing a buffer quite convoluted.

Move much of the remaining generic MM code to a new common location:
common/mm/mm.c. Also add a corresponding <nvgpu/mm.h> header. This
mostly consists of init and cleanup code to handle the common MM
data structures like the VIDMEM code, address spaces for various
engines, etc.
A few more indepth changes were made as well.
1. alloc_inst_block() has been added to the MM HAL. This used to be
defined directly in the gk20a code but it used a register. As a
result, if this register hypothetically changes in the future,
it would need to become a HAL anyway. This path preempts that
and for now just defines all HALs to use the gk20a version.
2. Rename as much as possible: global functions are, for the most
part, prepended with nvgpu (there are a few exceptions which I
have yet to decide what to do with). Functions that are static
are renamed to be as consistent with their functionality as
possible since in some cases function effect and function name
have diverged.

This change contains a generic cleanup of linux dependent parts of the
dbg_gpu_gk20a.* files. The following changes have been made
1) Moving methods into ioctl_dbg.* inside common/linux/
2) The structures dbg_session_gk20a and dbg_session_channel_data have
been split into two parts. struct device *dev is removed from
struct dbg_session_gk20a and instead packed into struct
dbg_session_gk20a_linux alongwith dbg_session_gk20a and is moved into
ioctl_dbg. dbg_session_gk20a is now rid of any linux dependencies and
remains in dbg_gpu_gk20a. Similarly, struct file is removed from
struct dbg_session_channel_data and is now packed into struct
dbg_session_channel_data_linux alongwith dbg_session_channel_data and
is moved into ioctl_dbg. struct dbg_session_channel_data is now rid of
linux dependencies and remains in dbg_gpu_gk20a.
3) A callback function is added in order to release the
dbg_session_channel_data.
