Log Message:
Fully implement bus_space(9) access to the z8530 SCC registers.
This adds the missing wbflush() calls after writing register data.

At same time tidy up several comments and make several KNF changes.

XXX: The z8530 MI driver doesn't support bus_space access to the registers
     (lacks a hook for storing a bus space tag, and stores register
     addresses directly)
     Until other ports catch up (this is the first) we have overlayed
     the missing data in the MD structures
