Debarshi Dutta 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.
