[PATCH 04/29] drm/amd/display: fix dpms_off issue when disabling bios mode

[Tom Chung]

From: Zhongwei Zhang <zhongwei.zh...@amd.com>

[Why]
disable_vbios_mode_if_required() will set dpms_off to false
during boot when pixel clk dismatches with driver requires.
This will cause extra backlight on and off if OS call 2
times setmode.

[How]
Set dpms_off to true to keep power_off and
let OS control BL by display's powerState.
