video: imx: Add LCDIF driver
Add support for the LCD interfaces (LCDIF1/2). When probed, these
interfaces request numerous clocks and power domains, attach the bridge
and look for a panel in order to retrieve its capabilities and
properties.
There is a similar existing driver in the upper folder for other i.MX
targets, I discovered this driver a bit late. It is not targeting the
i.MX8MP and I have no idea how different can the LCDIF be on this SoC,
but I did not manage to get it work, especially because it is not fully
compliant with the device-model, especially on the clocks/power
management side which is all ad-hoc. This is normal though, it was
contributed more than ten years ago.
