Jake Burkholder 6bfa8a2ef2 Split this into bus specific front end(s), so that it can be used by ppc.
This abstracts out all the differences I could see between the netbsd
sparc64 and macppc zs drivers.   In particular the offsets of the csr and
data registers are different, so we use a separate bus handle for each and
use bus_space_subregion to add the bus specific offsets.
