Deepak Nibade 7a4ecc8966 gpu: nvgpu: make debugger register access ELPG protected 
Some of the APIs that access debugger register are not protected
from ELPG. This might trigger PRI access timeouts for corresponding
registers if GR engine is power gated.

Add nvgpu_pg_elpg_protected_call() to protect against ELPG.

Bug 2820066
