[Qemu-devel] [PATCH 7/7] arm/highbank: enable PSCI emulation support

[Rob Herring <robherring2@gmail.com>]

From: Rob Herring <rob.herring@linaro.org>

Enable PSCI enulation on highbank and midway platforms.

Note that this requires fixing the PSCI function IDs in the DTB to match
what QEMU is using. This should get fixed.
