Debarshi Dutta 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

Jira NVGPU-597
