ppc/pnv: Introduce PnvChipClass::xscom_core_base() method 

The pnv_chip_core_realize() function configures the XSCOM MMIO subregion
for each core of a single chip. The base address of the subregion depends
on the CPU type. Its computation is currently open-code using the
pnv_chip_is_powerXX() helpers. This can be achieved with QOM. Introduce
a method for this in the base chip class and implement it in child classes.
