Alpha 8200: Do some compilation cleanup. Conditionalize some IDE stuff

Browse Source 
based upon presence/absence of ISA (there is no ISA bus on an 8200- okay,
well, there *could* be one in a DWLPX tray, but we don't support it)).

Most importantly change the interrupt resource map to cover a whole 16
bits. The 8200 uses 16 bit interrupt vectors which we construct that
contain the I/O-board, hose, an pci slot in them, and then we write these
vectors into the appropriate DWLPX registers. At any rate, a flat array
of 64 'IRQs' isn't enough.
