ARM: uniphier: change the external bus address mapping
In UniPhier SoCs before ProXstream2 and PH1-LD6b, two address spaces
0x00000000 - 0x0fffffff
0x40000000 - 0x4fffffff
are both mapped to the external bus (also called system bus),
so either was OK.
In the newest two SoCs, the former (0x00000000 - 0x0fffffff) is
assigned for the serial NOR interface.
Going forward, use the latter for the external bus.
