780a41f3ca 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.

7dd4094f1a Add a driver for the Zilog 8530 dual uart found in Ultra 1s and Ultra 2s.
With a 1 byte transmit fifo, 3 byte receive fifo, and wierd multiplexed I/O
designed for a Z80 cpu, this chip redefines suckage.

Based on the openbsd and netbsd drivers.  Only really works as a console,
modem support is not complete since I can't test it.
