[PATCH] ARM: 2747/1: allow platforms to provide their own iomap implementation



Patch from Lennert Buytenhek

This patch conditionalises the io{read,write}{8,16,32} defines and the
prototypes for ioport_map/ioport_unmap in asm-arm/io.h on ioread8 not
already having been defined.  This is done so that platforms can provide
their own implementation of the iomap API, ixp2000 for example needs
this.
