dt-bindings: display: imx: ldb: Add i.MX8qxp LDB dual channel mode documentation
i.MX8qxp LDB dual channel mode uses two LDB channels from two LDB
instances, while all other LDB variants in other SoCs use two LDB
channels from one LDB instance. This patch adds documentation
for the special case of i.MX8qxp LDB dual channel mode.
