[Qemu-ppc] [PATCH v4 1/2] target/ppc/cpu-models: set POWER9_v1.0 as POWER9 DD1

[Laurent Vivier]

CPU_POWERPC_POWER9_DD1 is 0x004E0100, so this is the POWER9 v1.0.

When we run qemu on a POWER9 DD1 host, we must use either
"-cpu host" or "-cpu POWER9", but in the latter case it fails with

    Unable to find sPAPR CPU Core definition

because POWER9 DD1 doesn't appear in the list of known CPUs.

This patch fixes this by defining POWER9_v1.0 with POWER9 DD1
PVR instead of CPU_POWERPC_POWER9_BASE. It also add POWER_v2.0
with POWER9 DD2 PVR to avoid to trigger kernel POWER9 DD1 workaround
in TCG mode.
