Log Message:
sync with netbsd-current, approved by releng-1-5.
sys/dev/pcmcia/if_cnw.c 1.11 -> 1.13
sys/dev/pcmcia/if_cnwreg.h 1.2 -> 1.3

use memory mapped address, instead of i/o memory access, for control
registers.  rationale:
- Netwave cards choke if we map i/o memory to >= 0x400
- even though, CIS tuple talks nothing about it
- it is not possible to specify range in pcmcia_io_map
- it would be very bad to do a try-and-error bus_space allocation for
  i/o memory regions < 0x400
- we can have exactly the same functionality with memory mapped access
this should correct PR 10139.

the memory mapped access idea was from WIDE wildboar/bsdi cnw code.
