From: Zhongwei <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 backlight by
display's powerState.
