Two fixes:

(1) Fix pcib_read/write_config prototypes.
(2) When contrainting a resource request for a 'subtractive' bridge,
    it is important to select a range outside the base/limit
    registers, since those are the only values known to not
    possibly work.  On my HP laptop, the base bridge excludes I/O
    ports 0xa000-0xafff, however that was the range we were passing
    up the tree.  Instead, when a range spans the "hole" we now
    arbitrarily pick the range just above the hole to allocate from.

All of my rl and xl cards, at a minimum, started working again on this
laptop with those fixes.
