Separate out new API gr_gp10b_set_ctxsw_preemption_mode()
which will check requested preemption modes and take appropriate
action for each preemption mode
This API will also do some sanity checking for valid
preemption modes and combinations
Define API set_preemption_mode() for gp10b which will set the
preemption modes passed as argument and then use
gr_gp10b_set_ctxsw_preemption_mode() and
update_ctxsw_preemption_mode() to update preemption mode
Legacy path from gr_gp10b_alloc_gr_ctx() will convert
flags NVGPU_ALLOC_OBJ_FLAGS_* into appropriate preemption modes
and then call gr_gp10b_set_ctxsw_preemption_mode()
New API set_preemption_mode() will use new flags
NVGPU_GRAPHICS/COMPUTE_PREEMPTION_MODE_* and set and update
ctxsw preemption mode
In gr_gp10b_update_ctxsw_preemption_mode(), update graphics
context to set CTA premption mode if mode
NVGPU_COMPUTE_PREEMPTION_MODE_CTA is set
Also, define preemption modes in nvgpu-t18x.h
and use them everywhere
Remove old definitions of modes from gr_gp10b.h

The server only releases ownership of the ctxsw buffer mappings
after the GR ctx has been released. Update the sequence to
account for this.

Some of the allocated buffers are used during normal graphics
processing. Mark them as GPU cacheable to improve performance.

gp10b introduces support for preemption (GfxP and CILP).
Add a new interface to allow allocating buffers needed
to support this functionality.
