gpu: nvgpu: add supported preemptions to gpu characteristics

Browse Source 
Add below flag fields to gpu characteristics to indicate
supported and default preemption modes on platform for
graphics and compute

__u32 graphics_preemption_mode_flags;
__u32 compute_preemption_mode_flags;
__u32 default_graphics_preempt_mode;
__u32 default_compute_preempt_mode;

Add struct nvgpu_preemption_modes_rec to struct gr_gk20a
to store these values locally

Use platform specific get_preemption_mode_flags() to
get the flags and define gk20a/gm20b specific
get_preemption_mode_flags() API
