3.5.7.8 -stable review patch.  If anyone has any objections, please let me know.

------------------

From: Alex Deucher <alexander.deucher@amd.com>

commit e8fc41377f5037ff7a661ea06adc05f1daec1548 upstream.

vbios values are wrong leading to colors that are
too bright.  Use the default values instead.
