Hirokazu Takata 46ea178b7a [PATCH] m32r: Update _port2addr to use NONCACHE_OFFSET
Modify _port2addr*() routines in arch/m32r/kernel/io_*.c to use
NONCACHE_OFFSET instead of hard-coding of a constant address.

This modification is also required to support an M3A-ZA36 FPGA eva board in
case an MMU-less synthesizable m32r core is used.
