[PATCH v3 3/7] dt-bindings: display: bridge: Repurpose lvds-encoder

[Fabrizio Castro <fabrizio.castro@bp.renesas.com>]

In an effort to repurpose lvds-encoder.c to also serve the
function of LVDS decoders, we ended up defining a new "generic"
compatible string, therefore adapt the dt-bindings to fit the
new purpose.

v2->v3:
* Extracted conversion to lvds-codec as per Rob's comment
v1->v2:
* Converted to dt-schema as per Neil's comment

+  require any configuration.
+
+  LVDS is a physical layer specification defined in ANSI/TIA/EIA-644-A. Multiple
+  incompatible data link layers have been used over time to transmit image data
+  to LVDS panels. This binding targets devices compatible with the following
+  specifications only.
