Subject: [PATCH v2 5/6] ARM: dts: sun7i: add pinmux setting for RGB888 output for LCD0

On the A20, as well as many other Allwinner SoCs, the PD pingroup has
the LCD0 RGB output functions.

Add a pinmux setting for RGB888 output from LCD0, so boards and tablets
with parallel RGB LCD panels may reference it.
