The R-Car LVDS encoder driver implements the bridge .mode_set() operation for the sole purpose of storing the mode in the LVDS private data, to be used later when enabling the encoder. Switch to the bridge .atomic_enable() and .atomic_disable() operations in order to access the global atomic state, and get the mode from the state instead. Remove both the unneeded .mode_set() operation and the display_mode and mode fields storing state data from the rcar_lvds private structure. As a side effect we get the CRTC from the state, replace the CRTC pointer retrieved through the bridge's encoder that shouldn't be used by atomic drivers. While at it, clarify a few error messages in rcar_lvds_get_lvds_mode() and turn them into warnings as they are not fatal.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
