The Arm PL110 and PL111 are IP blocks that provide a display engine with
an LCD interface, being able to drive a variety of LC panels.
Convert the binding over to DT schema, to the DTs can be automatically
checked.
This still contains the deprecated "arm,pl11x,tft-r0g0b0-pads" property,
because this is used by several DTs in the tree.
