ppc/pnv: introduce new skiboot platform properties
Newer skiboots (after 6.3) support QEMU platforms that have characteristics closer to real OpenPOWER systems. The CPU type is used to define the BMC drivers: Aspeed AST2400 for POWER8 processors and AST2500 for POWER9s. Advertise the new platform property names, "qemu,powernv8" and "qemu,powernv9", using the CPU type chosen for the QEMU PowerNV machine. Also, advertise the original platform name "qemu,powernv" in case of POWER8 processors for compatibility with older skiboots.
