This series add SMP brinup support for mediatek SoCs. This is based
on v4.1-rc1.

There are 2 similar but different SMP bringup up methods on Mediatek
mt65xx and mt81xx. On MT8135 & MT8127, system boots with a trustzone
firmware. Others, like MT6589, doesn't have trustzone, and run kernel
directly in secure world.

Patch 1~3 fix issues in mtk_timer(GPT) and enable arch timer support.
Patch 4,5 add support for cpu enable-method "mediatek,mt65xx-smp" and
"mediatek,mt81xx-tz-smp", which support Mediatek SMP bringup for non-TZ
and TZ platform.
Patch 6,7 finally enable SMP bringup for mt8135 and mt8127.
