Add LVDS RGB media bus formats
This patch adds three new RGB media bus formats that describe 18-bit or 24-bit samples transferred over an LVDS bus with three or four differential data pairs, serialized into 7 time slots, using standard SPWG/PSWG/VESA or JEIDA data ordering.

<para>On LVDS buses, usually each sample is transferred serialized in
|
||||
seven time slots per pixel clock, on three (18-bit) or four (24-bit)
|
||||
differential data pairs at the same time. The remaining bits are used for
|
||||
control signals as defined by SPWG/PSWG/VESA or JEIDA standards.
|
||||
The 24-bit RGB format serialized in seven time slots on four lanes using
|
||||
JEIDA defined bit mapping will be named
|
||||
<constant>MEDIA_BUS_FMT_RGB888_1X7X4_JEIDA</constant>, for example.
