This patch cleans up some old cruft in the manipulation of the LVDS
interface registers and fixes the blanking code to work with various DVI
flat panels.

Since this is all very sensitive stuff, I'm posting the patch here for
testing before submitting it upstream, though Andrew is welcome to put it
in -mm.

It also fix some problems with getting the right PLL setup on recent Mac
laptops, replacing the old hard coded list of values with cleaner code that
"probes" the PLL setup done by the firmware.
