[PATCH v2 0/4] arm: mediatek: Add support for GIC interrupt polarity extension.

[Joe.C]

This series add support for mediatek GIC interrupt polarity extension.
Several components in mediatek SoC have low level triggered interrupt and
require this support.

This also correct 6589 timer irq polarity. Previous version works because
6589 boot loader already set correct polarity for timer interrupt.

The patch set is based on Matthias's Mediatek basic support for v3.17 [1].

v2:
- Make mt6589.dtsi changes as a separate commit as Matthias suggest.
