Similarly for the Framework 13 panels already handled in those quirks,
the 16 can be helped by the same kind of patch.

I have run this on my own 16 for multiple months (hard coding the value to
0 before the quirks made it upstream) and it has resulted in a darker
minimum brightness (as expected) and no issues.

The Framework community threads between the 13 and 16 for this improvement
are the same one, so user reports in the link below will be mixed and
likely more focused on the 13.
