Subject: [PATCH v4, 0/3] add h264 decoder driver for mt8186

Firstly, add mt8186 compatible and private data, then add document for

architecture, need to add new interface for h264 hardware decoder.

Patche 1 add mt8186 compatible and private data.
Patche 2 add mt8186 compatible document.
Patche 3 add h264 single core driver.
