We don't use the VmmOps trait directly for manipulating memory in the
core of the VMM as it's really designed for the MSHV crate to handle
instruction decoding. As I plan to make this trait MSHV specific to
allow reduced locking for MMIO and PIO handling when running on KVM this
use should be removed.
