  arm64: KVM: Enable minimalistic support for Cortex-A53 (2014-05-25 20:05:30 +0200)

----------------------------------------------------------------
Changed for the 3.16 merge window.

This includes KVM support for PSCI v0.2 and also includes generic Linux
support for PSCI v0.2 (on hosts that advertise that feature via their
DT), since the latter depends on headers introduced by the former.

Finally there's a small patch from Marc that enables Cortex-A53 support.
