Some buffers like userd are physically addressed. If nvlink is
enabled, or device is not iommuable, this requires buffer to be
physically contiguous.
Add NVGPU_DMA_PHYSICALLY_ADDRESSED to identify such buffers, in
order to force physically contiguous allocation, only in above
cases.

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

CBC base needs to be aligned to 64KB. On Linux this is
achieved making compbit backing size multiple of 64KB.
However QNX nvmap alloc function does not allocate
memory aligned to requested size and needs to overallocate
to satisfy alignment requirement. Make cbc alloc function OS
specific to be able to modify QNX code.
Also align cbc base address to 64KB before writing to CBC BASE
register.
