Marcel Moolenaar cea4d8752f o Move ISA specific code from ppc.c to ppc_isa.c -- a bus front-
end for isa(4).
o  Add a seperate bus frontend for acpi(4) and allow ISA DMA for
   it when ISA is configured in the kernel. This allows acpi(4)
   attachments in non-ISA configurations, as is possible for ia64.
o  Add a seperate bus frontend for pci(4) and detect known single
   port parallel cards.
o  Merge PC98 specific changes under pc98/cbus into the MI driver.
   The changes are minor enough for conditional compilation and
   in this form invites better abstraction.
o  Have ppc(4) usabled on all platforms, now that ISA specifics
   are untangled enough.
