xen: arm: enable aborts on all physical processors.
I'm not sure how this ended up in construct dom0 where it only affects the
boot cpu and doesn't logically fit.
Enable aborts at the same time as we enable interrupts.
I'm not sure what the behaviour of an "abort worthy" operation while aborts
are disable is, but it must surely be worse than calling do_unexpected_trap,
which is what happens from now on.
