gpu: nvgpu: move force preemption flags to gr_ctx_desc

Browse Source 
Debug boolean flags force_preemption_gfxp and force_preemption_cilp are
right now stored in gr_gk20a.ctx_vars struct
These flags logically are property of gr.ctx units since they indicate
whether each context should be forced to gfxp/cilp preemption mode by
default

Move these flags to struct nvgpu_gr_ctx_desc and remove them from
gr_gk20a.ctx_vars

Expose below APIs from gr.ctx unit to check if flags are set
nvgpu_gr_ctx_desc_force_preemption_gfxp()
nvgpu_gr_ctx_desc_force_preemption_cilp()

Move debugfs creation code to create corresponding debugfs to
gr_gk20a_debugfs_init() and change debugfs type from "u32" to "file"

Struct gr.gr_ctx_desc is created only during first poweron.
Return error if this struct is not available.

Remove unnecessary initialization of these variables from platform
specific probe functions
