MLK-23292-1 arm64: dts: fsl-imx8dx-mek: Add IT6263 LVDS2HDMI dual channel support

Browse Source 
This patch adds IT6263 LVDS to HDMI transmitter dual channel support.
The transmitter works with LDB split mode.
fsl-imx8dx-mek-it6263-lvds0-dual-channel.dts uses LDB1 channel0 as the
channel to transmit odd pixels and LDB2 channel0 as the channel to
transmit even pixels.  fsl-imx8dx-mek-it6263-lvds1-dual-channel.dts
swaps the channels to transmit odd/even pixels.
