Warner Losh c3ee5891b9 First draft of common code between pccbb and pcic drivers for talking
to ExCA register sets.  These registers exist in both ISA and PCI
devices in a couple different ways, and this will provide a common
base for future building.  This code is a rehash of the pccbb 16-bit
code, which was a rehash of the pcic code, which was a rehash of the
netbsd i82365 code.  More hashing to come.
