sh: Kill off broken type 1 PCI config access checks.

Browse Source 
The host controllers only support type 1, so there's not much else to
test for. Some of the older controllers also supported type 2 accesses,
but we've never supported those, and likely never will. Beyond that, the
P1SEG test is meaningless for 32-bit mode, so rather than refactoring it,
just kill the type 1 test off completely.
