Thomas Zimmermann 5415bec18c drm/mgag200: Force 32 bpp on the console 
G200ER does not seem to support 24 bpp, so force the console to
use 32 bpp. The problem got introduced when commit 73f54d5d96
("drm/mgag200: Remove special case for G200SE with <2 MiB") changed
the preferred color depth from 32 bit to 24 bit.

A setting of 24 is the correct color depth, but G200ER doesn't seem
to be able to use the respective RGB888 color format. Using 24-bit
color with forced 32 bpp works around the problem.
