powerpc/fsl-diu-fb: Support setting display mode using EDID
Adds support for encoding display mode information in the device tree using verbatim EDID block. If the EDID entry in the DIU node is present, the driver will build mode database using EDID data and allow setting the display modes from this database. Otherwise display mode will be set using mode entries from driver's internal database as usual. This patch also updates device tree bindings.
