After setting 'Y' in disable_bigpage, in native SMMU case,
we could still see 64K GMMU pages beeing used.
Fixed the following:
- enforce disable_bigpage in nvgpu_vm_map
- update GPU characteristics so that new clients know
whether or not big pages are enabled. For instance
this may affect how CUDA requests memory mapping.

Refactor the sync_debugfs LTC HAL op so that the logic to enable
or disable LTC goes to common code nvgpu_ltc_sync_enabled() and
the LTC HAL set_enabled only performs the hardware register access.
Create a new common function nvgpu_init_ltc_support() to initialize
the LTC software variable, and move hardware initialization of LTC to
be called from it.

Reorganize HAL initialization to remove inheritance and construct
the gpu_ops struct at compile time. This patch covers the debug
and dbg_session_ops sub-modules of the gpu_ops struct.
Perform HAL function assignments in hal_gxxxx.c through the
population of a chip-specific copy of gpu_ops.

Move field "struct device *dev" from struct gk20a to struct
nvgpu_os_linux. The field is valid only for Linux.

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
