drm/amd/display: Add MSF panel to DPCD 0x317 patch list
This 8.4 inch panel is integrated in the Ayaneo Kun handheld
device. The panel resolution is 2560×1600, i.e. it has
portrait dimensions.
Decoding the EDID shows:
Manufacturer: MSF
Model: 4099
Display Product Name: 'TV080WUM-NL0 '
Judging from the product name this might be a clone of a
BOE panel, but with larger dimensions.
Panel frequently shows non-functional backlight control. Adding
some debug prints to update_connector_ext_caps() shows that
something the OLED bit of ext_caps is set, and then the driver
assumes that backlight is controlled via AUX.
Forcing backlight control to PWM via amdgpu.backlight=0 restores
backlight operation.
