Subject: [PATCH] sh: pci - fix the start address of IO ports area in
 RTS7751R2D.


sh: pci - fix the start address of IO ports area in RTS7751R2D.

This patch replaces the start address in 'sh7751_io_resource'
in arch/sh/drivers/pci/ops-rts7751r2d.c. The value must be
used for any PCI IO port access such as in*()/out*().

I drew upon the following patch:
