gpu: nvgpu: move debugfs code to linux module

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
