Russell King 080fc66fb5 ARM: Bring back ARMv3 IO and user access code
This partially reverts 357c9c1f07
(ARM: Remove support for ARMv3 ARM610 and ARM710 CPUs).

Although we only support StrongARM on the RiscPC, we need to keep the
ARMv3 user access code for this platform because the bus does not
understand half-word load/stores.
