[RFC v2 22/22] ARM: keystone: add switch over to high physical address range

Keystone platforms have their physical memory mapped at an address outside the 32-bit physical range. A Keystone machine with 16G of RAM would find its memory at 0x08 - 0x0b. For boot purposes, the interconnect supports a limited alias of some of this memory within the 32-bit
