7e1dbd8303 gpu: nvgpu: move header location of gk20a.h 
1) Update header path of gk20a.h files present in os/
to <nvgpu/gk20a.h>

2) os_fence_android_sema.c indirectly was dependent on gk20a.h via
semaphore.h. So, added #include <nvgpu/gk20a.h> in
os_fence_android_sema.c and replaced the header with forward
declaration of struct gk20a in semaphore.h

69be500c0b gpu: nvgpu: debugfs node to enable/disable ltc_illegal_compstat intr 
Added debugfs node under ltc directory with name:
intr_illegal_compstat_enable

Enabling/disabling of ltc_illegal_compstat intr is
possible through debugfs node.

Since ltc state is lost with rail gate, this setting is
cached and will be populated during ltc initialization.
