From: Stuart Yoder <stuart.yo...@freescale.com>
For 32-bit, CONFIG_EPAPR_PARAVIRT pulls in both epapr_paravirt.c
and epapr_hcalls.c which contains the 32-bit paravirt idle loop.
For 64-bit, the paravirt idle loop is in idle_book3e.S and that
source file is included only if CONFIG_PPC_BOOK3E_64 defined.
This patch makes that dependency for 64-bit explicit.
