Subject: [PATCH] drm: panel-backlight-quirks: Add Minisforum V3 SE

Exactly the same situation as with the Framework 13. Value from
ATIF is 12, which is quite bright as a minimum.

Additionally, disabling the custom curve produces a much more granular
control, especially at lower brightness values. For now this can be done
by the end-user by using `amdgpu.dcdebugmask=0x40000`.
