[src/trunk]: src/sys/dev/ic Make colour depths higher than 8bit work in X.
details: https://anonhg.NetBSD.org/src/rev/ad2a7fdbf641

description:
Make colour depths higher than 8bit work in X.
Now igsfb will switch to 16 or 32 bit colour when entering graphics mode,
depending on available video memory and the given mode.
While there re-initialize the colour map etc. when leaving graphics mode.
