arm/ptw: Honour WXN/UWXN and SIF in short-format descriptors
Currently the handling of page protection in the short-format
descriptor is open-coded. This means that we forgot to update
it to handle some newer architectural features, including:
* handling of SCTLR.{UWXN,WXN}
* handling of SCR.SIF
Make the short-format descriptor code call the same get_S1prot()
that we already use for the LPAE descriptor format. This makes
the code simpler and means it now correctly honours the WXN/UWXN
and SIF bits.
