feat(smmu): configure SMMU Root interface

This change performs a basic configuration of the SMMU root registers
interface on an RME enabled system. This permits enabling GPC checks
for transactions originated from a non-secure or secure device upstream
to an SMMU. It re-uses the boot time GPT base address and configuration
programmed on the PE.
The root register file offset is platform dependent and has to be
supplied on a model command line.
