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

[Joe.C]

Hi, ARM soc maintainers,

Please help to review this series, I think this should go through 
ARM soc tree.

We plan to upstream drivers for MT8135. MT8135 is a big/little soc
featuring 2 CA7 + 2 CA15, and sharing many similar IP components with
mt65xx. Many components of 65xx series & 8135 require this support.
