[Qemu-devel] [PULL 12/18] spapr: Move spapr_cpu_init() to spapr_cpu_core.c

[David Gibson <david@gibson.dropbear.id.au>]

From: Bharata B Rao <bharata@linux.vnet.ibm.com>

Start consolidating CPU init related routines in spapr_cpu_core.c. As
part of this, move spapr_cpu_init() and its dependencies from spapr.c
to spapr_cpu_core.c

No functionality change in this patch.

[dwg: Rename TIMEBASE_FREQ to SPAPR_TIMEBASE_FREQ, since it's now in a
 public(ish) header]
