The MediaTek DRM has a block called mmsys, which sets the routing and enables the different blocks. This patch adds one line for the mmsys bindings description and changes the mmsys description to use the generic form of referring to a specific Soc.

Changes in v7:
- add hint to the mmsys binding document
- make mmsys description generic
- fix typo in commit message
