xen: arm: Enable physical address space compression (PDX) on arm

This allows us to support sparse physical address maps which we previously
could not because the frametable would end up taking up an enormous fraction
of RAM.

On a fast model which has RAM at 0x80000000-0x100000000 and
0x880000000-0x900000000 this reduces the size of the frametable from
478M to 84M.
