xen: arm: do not pretend to be a Cortex-A15 when running 32-bit guests

It is definitely wrong to do this when running on non-Cortex-A15 32-bit
hardware but even when running on 64-bit hardware it's not really necessary
and may cause more harm than good if the underlying processor is not all that
similar to an A15.
