[PATCH v5 3/5] soc: imx: imx8m-blk-ctrl: Scan subnodes and bind drivers to them

This particular block can have DT subnodes describing the LVDS LDB
bridge. Instead of misusing simple-bus to scan for those nodes, do
the scan within the driver.

Fixes: 94e6197dadc9 ("arm64: dts: imx8mp: Add LCDIF2 & LDB nodes")
