[PATCH 1/2] drm/imx: imx-ldb: disable LDB on driver bind

The LVDS signal integrity is only guaranteed when the correct enable sequence (first IPU DI, then LDB) is used. If the LDB display output was active before the imx-drm driver is loaded (like when a bootsplash was active) the DI will be disabled by the full IPU reset we do when loading the driver.
