In order for a guest with caches disabled to observe data written contained in a given page, we need to make sure that page is committed to memory, and not just hanging in the cache (as guest accesses are completely bypassing the cache until it decides to enable it). For this purpose, hook into the coherent_cache_guest_page function and flush the region if the guest SCTLR register doesn't show the MMU and caches as being enabled.
