[PATCH v2 1/4] imx-drm: imx-drm-core: Export imx_drm_encoder_get_mux_id

[Fabio Estevam]

From: Fabio Estevam <fabio.estevam@xxxxxxxxxxxxx>

When building imx_v6_v7_defconfig with imx-drm drivers selected as modules, we
get the following build error:

ERROR: "imx_drm_encoder_get_mux_id" [drivers/staging/imx-drm/imx-ldb.ko] undefined!

Export the required function to avoid this problem.
