Fix one such THING in code to match comment. Sort IO_GSC* into numeric order and update comments about the gaps. Sort common SCSI addresses into alphabetical order. Remove bogus comments about com ports having i/o size 4. Uniformize whitespace. Uniformize case in hex digits. This file is very incomplete. In particular, it doesn't mention any network cards. This doesn't matter much for the base addresses, but it means that the comments about which addresses are free are mostly bogus. The i/o sizes are unreliable because of split address ranges for many devices (VGA, wd). The i/o sizes are incomplete. In particular, there are no sizes for SCSI controllers. The bt driver still returns a truth value instead of a size.
