Contrast is pretty generic for all MediaQ chips (in fact, it's just a
dirty hack, not real contrast). But I'm surprised to see brightness
worked too.

Also what I see from mq1178 register dump Koen sent me, h2200 doesn't
use any GPIO pins from MediaQ, so mq_base->set_GPIO statements should
not be used in h2200_lcd.c. On other hand, I think instead of MediaQ
GPIO1 on Axim on h2200 the GPIO_NR_H2200_LCD_POWER_ON PXA GPIO should be
used instead (if LCD_POWER doesn't mean here power to the MediaQ chip).
I would try first in HaRET to switch on/off GPIO67 and see what happens.
The command for this is "SET GPLR(67) 0 or 1".
