Subject: [PATCH 3.18 014/124] Revert "ARM: 8457/1: psci-smp is built only for SMP"

3.18-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Amit Pundir <amit.pundir@...aro.org>

This reverts commit dbcfee724255ae171af51aaa56d8c5b78342adc9 which is
commit be95485a0b8288a93402705730d3ea32f9f812b9 upstream.

Upstream commit be95485 (ARM: 8457/1: psci-smp is built only for SMP)
was intended to fix the build error for configs with CONFIG_SMP=n and
CONFIG_ARM_PSCI=y, but it end up introducing a build error when
cherry-picked on 3.18.y.

This patch resulted in redefinition of psci_init() and broke the
build for every build config in 3.18.y with CONFIG_SMP=n and
CONFIG_ARM_PSCI=y.
