arm/ptw: Handle atomic updates of page tables entries in MMIO during PTW.
I'm far from confident this handling here is correct. Hence
RFC. In particular not sure on what locks I should hold for this
to be even moderately safe.
The function already appears to be inconsistent in what it returns
as the CONFIG_ATOMIC64 block returns the endian converted 'eventual'
value of the cmpxchg whereas the TCG_OVERSIZED_GUEST case returns
the previous value.
