This patch adds psci comatible properties to support all mandatory
functions of PSCI-1.0, PSCI-0.2 and PSCI-0.1, and system suspend
can be supported in PSCI-1.0.
Signed-off-by: Fan Chen <fan.chen@mediatek.com>

Because PSCI-1.0 patches hadn't landed on mainline, this patch is
based on three patch sets below:
[0] http://www.spinics.net/lists/arm-kernel/msg425793.html
PSCI: system suspend support
[1] git://git.kernel.org/pub/scm/linux/kernel/git/mark/linux.git
psci/unification
[2] http://www.spinics.net/lists/devicetree/msg82017.html
[PATCH 0/6] drivers: firmware: psci: add basic v1.0 support
Before they are merged in, this patch still works fine with psci-0.2
support in current mainline.

As this binding is not yet upstream, I prefer not to take the patch.
Most probably the binding will have the name you indicated, but as DTS
bindings are representing an external API, we should be really careful
in changing them.
Cheers,
Matthias
