Why does the cache operation need to happen on the same CPU while the L1 caches

In current code, if we map a readonly memory space from host to guest
and the page is not currently mapped in the host, we will get a fault-pfn
and async is not allowed, then the vm will crash
We introduce readonly memory region to map ROM/ROMD to the guest, read access
is happy for readonly
Introduce write_readonly_mem in mmio-exit-info to indicate this exit is
caused by write access on readonly memslot
