hw/ppc/spapr_cpu_core: Add a proper check for spapr machine
QEMU currently crashes when the user tries to add a spapr-cpu-core
on a non-pseries machine:
$ qemu-system-ppc64 -S -machine ppce500,accel=tcg \
-device POWER5+_v2.1-spapr-cpu-core
hw/ppc/spapr_cpu_core.c:178:spapr_cpu_core_realize_child:
Object 0x55cee1f55160 is not an instance of type spapr-machine
Aborted (core dumped)
So let's add a proper check for the correct machine time with
a more friendly error message here.
