This rearranges a bit of code, and adds support for 36-bit physical addressing for configs that use a hashed page table. The 36b physical support is not enabled by default on any config - it must be explicitly enabled via the config system. This patch *only* expands the page table code to accomodate large physical addresses on 32-bit systems and enables the PHYS_64BIT config option for 86xx. It does *not* allow you to boot a board with more than about 3.5GB of RAM - for that, SWIOTLB support is also required (and coming soon).
