To support vidmem, pass g and mem_desc to the buffer memory accessor
functions. This allows the functions to select the memory access method
based on the buffer aperture instead of using the cpu pointer directly
(like until now). The selection and aperture support will be in another
patch; this patch only refactors these accessors, but keeps the
underlying functionality as-is.

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
