gpu: nvgpu: remove nvgpu_preemption_modes_rec struct

Browse Source 
g->ops.gr.get_preemption_mode_flags() hal is used to fetch information
on supported preemption modes and default preemption mode
Temporary struct nvgpu_preemption_modes_rec is used for this purpose
and is defined in gk20a/gr_gk20a.h right now.

Split above hal into two separate hals and move them to hal.gr.init unit
g->ops.gr.init.get_supported__preemption_modes()
g->ops.gr.init.get_default_preemption_modes()

These hals now return respective flags in pointers passed in function
parameter list, so there is no need to use temporary structure anymore
Hence delete struct nvgpu_preemption_modes_rec

Implement gm20b/gp10b chip specific hals in hal.gr.init unit.
Delete g->ops.gr.get_preemption_mode_flags() hal
