[PATCH v5 08/14] ARM: tegra: Make outer_disable() open-coded

[Dmitry Osipenko]

The outer_disable() of Tegra's suspend code is open-coded now since
that helper produces spurious warning message about secondary CPUs being
online. The secondaries are actually halted by the cpuidle driver on
entering into LP2 idle-state. This fixes a storm of warnings once LP2
idling state is enabled on Tegra30.
