[PATCH 6/6] arm: a37xx: pci: Increase PCIe MEM size from 16 MiB to 128 MiB - 64 KiB

For some configurations with more PCIe cards and PCIe bridges 16 MiB of
PCIe MEM space is not enough. Since TF-A already allocates a 128 MiB CPU
window for PCIe and IO port space is only 64 KiB in total, use all the
remaining space for PCIe MEM.
