the chipset space init functions multiple times, since that would clobber
extent allocations made between the two calls. Also, deal with the
fact that the APECS and LCA no longer shared common chipset functions.

move probe and setup code into common functions. always probe (i.e.
...
even if PCI and the IDs are right), just for sanity, before declaring
success. Split the single 0x3b0 -> 0x3df allocation into three seperate
ones: 0x3b0 -> 0x3bc (leaving the 4 ports available for lpt),
0x3c0 -> 0x3cf, and 0x3d0 -> 0x3df. The former chunk has to be split
off if the lpt can exist there, and it's sort-of pretty to have each
group (based on second hex digit) have its own handle.

replace old PCI VGA driver with a common VGA back-end and ISA and PCI
...
front-ends. Unfortunately, because of the way ISA and PCI are currently
probed, if you have a PCI VGA board in your machine and both drivers
in your kernel, the ISA VGA driver may accidentally match the PCI board.
For now, the only solution to this is to not put both drivers in
the GENERIC kernels.
