drm/imx: imx-ldb: Register LDB channel1 when it is the only channel t…

…o be used

LDB channel1 should be registered if it is the only channel to be used.
Without this patch, imx_ldb_bind() would skip registering LDB channel1
if LDB channel0 is not used, no matter LDB channel1 needs to be used or
not.
