       z8530_read_port - Architecture specific interface function


       int z8530_read_port  (unsigned long p);


       p      port to read


       Provided  port  access  methods.  The  Comtrol  SV11 requires no delays
       between accesses and uses PC I/O. Some drivers may need a 5uS delay

       In the longer term this should become an architecture specific  section
       so  that  this can become a generic driver interface for all platforms.
       For now we only handle PC I/O ports  with  or  without  the  dread  5uS
       sanity delay.

       The  caller  must hold sufficient locks to avoid violating the horrible
       5uS delay rule.
