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.

Massive overhaul of exca to help with the isa efforts: o chip_name arrays ifdef'd out. o use the OLDCARD-like get/put functions so we can support differnt types of mappings. o Write the beggings of is this a valid exca device and introduce more chipset support. # this is partially a wip, but also needed because some other cahnges I've # made require some of these changes.
