[src/trunk]: src/sys/arch A debe can't feed both tcon at the same time.

description:
A debe can't feed both tcon at the same time.
AWIN_DEBE_MODCTL_OUT_SEL will select which tcon instance will get data
(0 for tcon0, 1 for tcon1).
In tcon, AWIN_TCON_CTL_SRC_SEL_DE0 selects the default debe for this
tcon instance: debe0 for tcon0, debe1 for tcon1.
So always connect tcon0 to debe0 and tcon1 to debe1.
now display modes 0, 1 and 2 works; display modes 3 and 4 needs more work.
