[src/trunk]: src/sys/dev/pci - clean up some testing & debugging goop
details: https://anonhg.NetBSD.org/src/rev/b530764d3560
branches: trunk
changeset: 822525:b530764d3560

description:
- clean up some testing & debugging goop
- 0xff is transparent, so restrict ourself to just 4 bit colour, all we need
for wscons
- support WSDISPLAYIO_GET_FBINFO etc. for wsfb, allow mmap()ing the fb etc.
