Subject: [PATCH v4 0/2] Add mt6580 basic chip support

Changes in v4:
1. Remove clocks node
2. Remove bootargs
3. Refine stdout-path setting

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
