[PATCH v5 2/5] dt-bindings: soc: imx8mp-media-blk-ctrl: Add LDB subnode into schema and example

[Marek Vasut <marex@xxxxxxx>]

Document the LDB bridge subnode and add the subnode into the example.
For the subnode to work, the block control must scan its subnodes and
bind drivers to them, do not misuse either simple-bus or simple-mfd
here.
