Add compatible string 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. However, except for the complete bit reshuffling, this is still LCDIF and it still works like one.

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.
