RADEON: implement support for posting cards based on x86 bios tables (untested)

This is based on the netbsd radeonfb driver by Garrett D'Amore.
The code is not hooked up yet, but should allow you to post cards
without needing to execute bios code.  This should be useful on
non-x86 platforms, for posting secndary cards, and for suspend/resume.
Works on legacy bioses only (no ATOM support).
