From: Stuart Yoder <stuart.yo...@freescale.com>
some restructuring of epapr paravirt init resulted in
ppc_md.power_save being set, and then overwritten to
NULL during machine_init. This patch splits the
initialization of ppc_md.power_save out into a postcore
init call.

-v3
-changed approach slightly, set flag in the dt scanning
code and just look at that flag in the initcall

-made idle flag static
