MLK-13929-3 video: Update LCDIF driver to support MIPI-DSI
The LCDIF provides video source for MIPI DSI host at DPI-2 interface.
When the LCDIF Framebuffer driver is enabled, it uses the panel
parameters setup by environments to create a panel device and register
it to DSI host driver and then enable the DSI host.
