Marek Vasut 9db35bb349 drm: lcdif: Add support for i.MX8MP LCDIF variant
Add support for i.MX8MP LCDIF variant. This is called LCDIFv3 and is
completely different from the LCDIFv3 found in i.MX23 in that it has
a completely scrambled register layout compared to all previous LCDIF
variants. The new LCDIFv3 also supports 36bit address space.

Add a separate driver which is really a fork of MXSFB driver with the
i.MX8MP LCDIF variant handling filled in.

Choose this option if you have an LCDIF or eLCDIF LCD controller.
Those devices are found in various i.MX SoC (including i.MX23,
i.MX28, i.MX6SX, i.MX7 and i.MX8M).
If M is selected the module will be called mxsfb.
