[PATCH 3/6] arm64: dts: Add a devicetree for the ARMv8 4xA53 4xA57 FVP

[broonie@kernel.org (Mark Brown)]

From: Mark Brown <broonie@linaro.org>

Add a dts file for ARMv8 fixed virtual platform which models a
big.LITTLE configuration for the architecture.  This is based on the
DT shipped by ARM but has been modified for mainline, removing features
not present in mainline and updating the CPU bindings for mainline.
