[PATCH] arm64: dts: mediatek: mt8173 PSCI-1.0 support

[fan.chen at mediatek.com]

From: Fan Chen <fan.chen at mediatek.com>

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 at 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.
