gpu: nvgpu: make the local function static

Fixed the following sparse warnings by making below APIs static:
- gk20a.c: warning: symbol 'gk20a_pm_restore_debug_setting' was not declared.
                    Should it be static?
- gr_gk20a.c: warning: symbol 'gr_gk20a_rop_l2_en_mask' was not declared.
	               Should it be static?
- gr_gm20b.c: warning: symbol 'gr_gm20b_rop_l2_en_mask' was not declared.
		       Should it be static?
