*	gpu: nvgpu: wait for gr.initialized before changing cg/pg	Debarshi Dutta	2019-05-09
\| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \|	set gr.initialized to false in the beginning of gk20a_gr_reset() and set it to true at the end of successful execution of gk20a_gr_reset. Use gk20a_gr_wait_initialized() to enable/disable cg/pg functions to make sure engine is out of reset and initialized.

*	gpu: nvgpu: add cg and pg function	Debarshi Dutta	2019-05-09
	Add new power/clock gating functions that can be called by other units. New clock_gating functions will reside in cg.c under common/power_features/cg unit. New power gating functions will reside in pg.c under common/power_features/pg unit. Use nvgpu_pg_elpg_disable and nvgpu_pg_elpg_enable to disable/enable elpg and also in gr_gk20a_elpg_protected macro to access gr registers. Add cg_pg_lock to make elpg_enabled, elcg_enabled, blcg_enabled and slcg_enabled thread safe.
