[Qemu-ppc] [PATCH v3] spapr_cpu_core: cleaning up qdev_get_machine() calls

[Greg Kurz]

This patch removes the qdev_get_machine() calls that are made
in spapr_cpu_core.c in situations where we can get an existing
pointer for the MachineState by either passing it as an argument
to the function or by using other already available pointers.

Credits to Daniel Henrique Barboza for the idea and the changelog
text.
