Now that we are about to make changes to how ArmVirtQemu reasons about the size of the address space, it would be better to get rid of this mapping of the entire address space, since it can get arbitrarily large without real benefit. So start by mapping the ECAM and translated I/O spaces explicitly, instead of relying on the early PEI mapping.
