x86, setup: un-resequence mode setting for VGA 80x34 and 80x60 modes
Impact: Fixes these modes on at least one system
The rewrite of the setup code into C resequenced the font setting and
register reprogramming phases of configuring nonstandard VGA modes
which use 480 scan lines in text mode. However, there exists at least
one board (Micro-Star MS-7383 version 2.0) on which this resequencing
causes an unusable display.
Revert to the original sequencing: set up 480-line mode, install the
font, and then adjust the vertical end register appropriately.
This failure was masked by the fact that the 480-line setup was broken
until checkin 5f641356127712fbdce0eee120e5ce115860c17f (therefore this
is not a -stable candidate bug fix.)
