[PATCH v2] FB driver for Cirrus GD5446 graphic hardware.

[Joel Sherrill]

Thanks.

I did the Makefile.am and configure.ac magic.
When you configure add USE_CIRRUS_GD5446=1
to the configure command line.

This should all be committed now. Please let me
know that this works for you and then we can
move on to the graphics toolkit.
