target-ppc: QOM'ify CPU
Embed CPUPPCState as first member of PowerPCCPU. Distinguish between "powerpc-cpu", "powerpc64-cpu" and "embedded-powerpc-cpu". Let CPUClass::reset() call cpu_state_reset() for now. Signed-off-by: Andreas Färber <afaerber@suse.de> Acked-by: David Gibson <david@gibson.dropbear.id.au>
