6777bd5ed2 gpu: nvgpu: add separate unit for gr/ctxsw_prog
Add separate new unit gr/ctxsw_prog that provides interface to access
h/w header files hw_ctxsw_prog_*.h

Add below chip specific files that access above h/w unit and provide
interface through g->ops.gr.ctxsw_prog.*() HAL for rest of the units

common/gr/ctxsw_prog/ctxsw_prog_gm20b.c
common/gr/ctxsw_prog/ctxsw_prog_gp10b.c
common/gr/ctxsw_prog/ctxsw_prog_gv11b.c

Remove all the h/w header includes from rest of the units and code.
Remove direct calls to h/w headers ctxsw_prog_*() and use HALs
g->ops.gr.ctxsw_prog.*() instead

In gr_gk20a_find_priv_offset_in_ext_buffer(), h/w header
ctxsw_prog_extended_num_smpc_quadrants_v() is only defined on gk20a
And since we don't support gk20a remove corresponding code

Add missing h/w header ctxsw_prog_main_image_pm_mode_ctxsw_f() for
some chips
Add new h/w header ctxsw_prog_gpccs_header_stride_v()

e24df49765 gpu: nvgpu: nvgpu_memcpy changes to linux os code
MISRA Rule 21.15 prohibits use of memcpy() with incompatible ptrs
to qualified/unqualified types.

To circumvent this issue we've introduced a new MISRA-compliant
nvgpu_memcpy() function.

While linux os code does not need to be MISRA-compliant this
change switches over all memcpy() uses to nvgpu_memcpy()
with appropriate casts applied to maintain consistency within
the nvgpu source base.

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
