Alexander Graf 5fd6a3e236 hvf: arm: Ignore cache operations on MMIO
Apple's Hypervisor.Framework forwards cache operations as MMIO traps
into user space. For MMIO however, these have no meaning: There is no
cache attached to them.

So let's just treat cache data exits as nops.

This fixes OpenBSD booting as guest.
