Geoff Levand 540270d82d [POWERPC] spufs: further abstract priv1 register access
To support muti-platform binaries the spu hypervisor accessor
routines must have runtime binding.

I removed the existing statically linked routines in spu.h
and spu_priv1_mmio.c and created new accessor routines in spu_priv1.h
that operate indirectly through an ops struct spu_priv1_ops.
spu_priv1_mmio.c contains the instance of the accessor routines
for running on raw hardware.
