The main task of imx encoders' ->prepare callbacks is to set bus_format,
bus_flags, di_vsync_pin and di_hsync_pin. We may create a structure named
imx_encoder to cache them. The atomic encoder callback ->disable may
replace ->prepare later, so let's remove ->prepare.

v3->v4:
* Fix wrong LVDS bus format translation issue in
imx_ldb_connector_get_modes() so that bus format could be determined
by panel instead of device tree.
This issue was found by Philipp Zabel.
v2->v3:
* Newly introduced.
The logic is picked from patch 07/10 in v2 to generate a self-contained
patch.
