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.
