0ffc5fa5e4 gpu: nvgpu: add clock gating support for HSHUB
Add BLCG and SLCG clock gating support for HSHUB unit on gv11b

Register list for BLCG and SLCG is auto generated with scripts.
Add HAL operations to enable/disable HSHUB clock gating

Re-generate gv11b reglist so that all the manually commented registers
are automatically deleted. Some of the unicast registers are also
deleted. We already have corresponding broadcast registers present.

Cherry-pick/manually port from dev-main

4d8ad643d6 gpu: nvgpu: wait for gr.initialized before changing cg/pg
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.

c81cc032c4 gpu: nvgpu: add cg and pg function
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.
