ARM: KVM: don't special case PC when doing an MMIO
Admitedly, reading a MMIO register to load PC is very weird. Writing PC to a MMIO register is probably even worse. But the architecture doesn't forbid any of these, and injecting a Prefetch Abort is the wrong thing to do anyway. Remove this check altogether, and let the adventurous guest wander into LaLaLand if they feel compelled to do so.
