valkyriefb: various fixes 

Valkyriefb and macfb will adopt the same card if they get the chance, so
remove valkyrie support from macfb. Also fix the "valkyriefb: can't do
832x624x8" problem reported by Raylynn Knight some time ago, by adding
vmode 13 support for CONFIG_MAC. Also add vmode 11 since that works too.
Make use of the monitor sense lines on 68k Macs too. Also some cleanups.
