imx media blk ctrl combined many small glue logic registers for display
, camera, power, clk and reset.

There are some discussion at
https://lore.kernel.org/all/4414669.ejJDZkT8p0@steina-w/
to define whole schema for this.

But there are some difficults to cover whole once.

Plan use two steps to complete it
- add all camera related property and subnode
- add all display related property and subnode
