Hi Krystoff, Laurent, Geert,

The RZ/G3E Soc has 2 LCD controller (LCDC), contain a Frame Compression
Processor (FCPVD), a Video Signal Processor (VSPD), Video Signal
Processor (VSPD), and Display Unit (DU).

 - LCDC0 supports DSI and LVDS (single or dual-channel) outputs.
 - LCDC1 supports DSI, LVDS (single-channel), and RGB outputs.

Add then two new SoC-specific compatible strings 'renesas,r9a09g047-du0'
and 'renesas,r9a09g047-du1'.
