Hello,

this patch fixes the VGA display for MIPS Malta (big endian, 32 bit).

I have no tests for other big endian targets (32 or 64 bit).
Do they have a working VGA display (then my patch must be restricted
to MIPS and/or 32 bit), or do they show wrong pixel columns with current
Qemu trunk, too?

Regards
Stefan
