ArmVirtualizationPkg/PciHostBridgeDxe: set Root Bridge apertures from PCDs

Our PciHostBridgeDxe module creates one root bridge on the one and only
host bridge. The resource apertures of the root bridge (bus range, IO
space, MMIO space) are configured with the "mResAperture" array, which at
the moment carries static values inherited from PcAtChipsetPkg.

Set the array as first thing from the PCDs that we parsed from the device
tree.
