ARM: dts: iwg22d-sodimm: Enable LCD panel

Browse source

On the Generic SODIMM Development Platform there is an RGB LCD panel
directly connected to the DU output. It uses the TPU0 as backlight, one
GPIO pull-up configuration for power enable, R[2:7], G[2:7], B[2:7],
VSYNC, HSYNC, DU0_DISP and, DU0_CLK as inputs.

There is no encoder between the DU and the panel, therefore the default
connector driver is used.

The two variants of the iW-G22D should be mutually exclusive, therefore
this patch also disables the RGB LCD display when the HDMI extension board
is used.
