drm/amd/display: Fix system resume lag issue

Browse source

[ Upstream commit 64c94cd9be ]

[Why]
System will try to apply idle power optimizations setting during
system resume. But system power state is still in D3 state, and
it will cause the idle power optimizations command not actually
to be sent to DMUB and cause some platforms to go into IPS.

[How]
Set power state to D0 first before calling the
dc_dmub_srv_apply_idle_power_optimizations(dm->dc, false)
