[PATCH] ppc/pnv: Set P10 core xscom region size to match hardware

[Nicholas Piggin]

The P10 core xscom memory regions overlap because the size is wrong.
The P10 core+L2 xscom region size is allocated as 0x1000 (with some
unused ranges). "EC" is used as a closer match, as "EX" includes L3
which has a disjoint xscom range that would require a different
region if it were implemented.
