The probe function needs to get ahold of the panel device tree
node, and it achieves that by using a combination of
of_graph_get_port_by_id, of_get_child_by_name, and
of_graph_get_remote_port_parent. We can achieve the same goal
by replacing those calls with a call to of_graph_get_remote_node
these days.

Add support for transparent LVDS decoders by adding a new
compatible string ("lvds-decoder") to the driver.
This patch also adds member connector_type to struct lvds_codec,
and that's because LVDS decoders have a different connector type
from LVDS encoders. We fill this new member up with the data
matching the compatible string.

lvds-encoder.c implementation is also suitable for LVDS decoders,
not just LVDS encoders.
Instead of creating a new driver for addressing support for
transparent LVDS decoders, repurpose lvds-encoder.c for the greater
good with this patch.
This patch only "rebrands" the lvds-encoder.c driver, to make it
suitable for hosting LVDS decoders support. The actual support for
LVDS decoders will come with a later patch.
