gpu: nvgpu: separate IOCTL to set preemption mode
Add separate IOCTL NVGPU_IOCTL_CHANNEL_SET_PREEMPTION_MODE
to allow setting preemption modes from UMD
Define preemption modes in nvgpu.h and use them everywhere
Remove mode definitions from mm_gk20a.h
Also, we support setting only one preemption mode in a channel
But it is possible to have multiple preemption modes (one from
graphics and one from compute) set simultaneously
Hence, update struct gr_ctx_desc to include two separate
preemption modes (graphics_preempt_mode and compute_preempt_mode)
API NVGPU_IOCTL_CHANNEL_SET_PREEMPTION_MODE also supports
setting two separate preemption modes i.e. one for graphics
and one for compute
Make necessary changes in code to support two preemption
modes
