Yongqiang Sun f03628232f drm/amd/display: Clear dmps off for eDP when resume.
This patch fixed secondary screen only S4 resume, eDP is unintentionally
light up due to incorrect dpms off flag.

When entering S4, dpms off flags are set to true via
set power state. During resume, eDP is light up by vbios, so the flags
should be changed to false to match the real state.
By change the flag properly, eDP is able to be turned off properly as per
OS request.

This change may affect S3/S4 Shut down resume IOIC, need to verify
those cases.
