plat: marvell: a70x0: reconfigure CP0 PCIE2 windows
In order to allow the use of PCIe cards such as graphics cards, whose
demands for BAR space are typically much higher than those of network
or SATA/USB cards, reconfigure the I/O windows so we can declare two
MMIO PCI regions: a 512 MB MMIO32 one at 0xc000_0000 and a 4 GB MMIO64
one at 0x8_0000_0000. In addition, this will leave ample room for an
ECAM config space at 0xe000_0000 (up to the ECAM maximum of 256 MB)
For compatibility with older kernels or firmware, leave the original
16 MB window in place as well.
