Support for per-page tables requires the SMMU aparture to be setup, on
some targets this is done statically in firmware, on others it's
expected to be requested in runtime by the driver, through a SCM call.
Marking the series as RFT, as this has been tested on a few different
modern platforms, but only with Qualcomm presence in EL2.
