drm: lcdif: Set and enable FIFO Panic threshold
In case the LCDIFv3 is used to drive a 4k panel via i.MX8MP HDMI bridge, the LCDIFv3 becomes susceptible to FIFO underflows, these lead to nasty flicker of the image on the panel, or image being shifted by half frame horizontally every second frame. The flicker can be easily triggered by running 3D application on top of weston compositor, like neverball or chromium. Surprisingly glmark2-es2-wayland or glmark2-es2-drm does not trigger this effect so easily.
Configure the FIFO Panic threshold register and enable the FIFO Panic mode, which internally boosts the NoC interconnect priority for LCDIFv3 transactions in case of possible underflow. This mitigates the flicker effect on 4k panels as well.

If a axi bus master with a higher priority do a lot of memory access FIFO underruns can be inspected. Increase the burst size to 256B to avoid such underruns and to improve the memory access efficiency.

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.
