rS292680: Extend Book-E to support >4GB RAM
Summary

With some additional changes for AIM, that could also support much
larger physmem sizes. Given that 32-bit AIM is more or less obsolete, though,
it's not worth it at this time.

Test Plan

Tested on a P5020 board with 8GB physical memory, clamped by the
device tree to 6GB. 8GB panics, likely due to autotuning issues.
