Subject: drm/amd/display: fix not calling ppsmu to trigger PME
Git-commit: 18b401874aee10c80b5745c9b93280dae5a59809
Patch-mainline: 5.4-rc1
References: bnc#1151927 5.3.5
[why]
dcn20_clk_mgr_construct was not initializing pp_smu, and PME call gets
filtered out by the null check
[how]
initialize pp_smu dcn20_clk_mgr_construct
