gpu: nvgpu: move dump_ctxsw_stats_on_channel_close flag to gr_ctx_desc

Browse Source 
Debug boolean flag dump_ctxsw_stats_on_channel_close is right now stored
in gr_gk20a.ctx_vars struct
This flag logically is property of gr.ctx units since it indicates
whether each context should dump ctxsw stats on channel/context close

Move this flag to struct nvgpu_gr_ctx_desc and remove it from
gr_gk20a.ctx_vars

Expose below API from gr.ctx unit to check if flag is set
nvgpu_gr_ctx_desc_dump_ctxsw_stats_on_channel_close()

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 this variable from platform
specific probe functions
