Fix AMD brightness issue on AUO panel

[AaronMa]

[Impact]
When change brightness quickly on gnome menu,
AUO panel will be stuck in previous brightness.

[Fix]
The TCON is random hung by PSR-SU.
Force enable ffu mode on PSR-SU panel.

[Test]
Tested on hardware, the brightness is changed as expected.

[Where problems could occur]
It may break AMD display.

The commit is already in v6.8-rc5,
the platform is not fully supported in Jammy 5.15,
So SRU oem-6.5 and mantic.
