ppc/pnv: Introduce PnvMachineClass and PnvMachineClass::compat
The pnv_dt_create() function generates different contents for the
"compatible" property of the root node in the DT, depending on the
CPU type. This is open coded with multiple ifs using pnv_is_powerXX()
helpers.
It seems cleaner to achieve with QOM. Introduce a base class for the
powernv machine and a compat attribute that each child class can use
to provide the value for the "compatible" property.
