Document a few more VBT structures and comment on VBIOS communication a
bit. There should be enough there now for a sufficiently motivated
developer to start implementing support for hotkeys and other features
on pre-IGD OpRegion machines.
Dump more panel data, including number of expected entries. Had to
refactor things a bit, but now each function should get size information
so further checking can be added more easily.
Make VBT parsing happen at driver init time rather than in each output init
function, to save time and better separate VBIOS code into i830_bios.[ch]. The
changes end up touching the output files due to field name changes, and allow
us to reorder & simplify our LFP mode detection code.
