From: yanyan kang <Yanyan.Kang at amd.com>

[why]
disable_az_endpoint has been skipped because
dc->debug.az_endpoint_mute_only = true.

[how]
set dc->debug.az_endpoint_mute_only false when PPLIB’s PME notification function
 pointer is not NULL at the dcn10_resource construct function,because right now
 SMU/PPLIB and DAL all have the AZ D3 force PME notification implemented. AZ D3 should work.
