[PATCH v3 0/2] Add mt6580 basic chip support

[mars.cheng-NuS5LvNUpcJWk0Htik3J/w]

This patch adds basic support for Mediatek's new 4-core chip, mt6580.
Based on v4.2-rc1.

This patch add basic support for Mediatek's new 4-core chip, mt6580.
Changes in v3:
1. Remove useless Change-Id
2. Add complete device tree binding in Documentation

Changes in v2:
1. Use stdout-path in device tree to indicate console
2. Remove board-specific bootargs
