Warner Losh 6dfd31d460 MFp4:
o Protect .h against multiple includes.
	o eliminate the pointers to the read/write routines.  The
	  bus_space_read routines can cope since we have the offset
	  field.
	o Print a warning if the requested map address is > 16M and
	  your chipset doesn't support the extended ExCA registers.
