The format is needed to calculate the link speed for the external DPHY configuration. It is not right to query the format from the source subdev. Add get_fmt and set_fmt pad operations so that the format can be configured and correct bpp be selected. Initialize and use the v4l2 subdev active state to keep track of the active formats. Also propagate the new format from the sink pad to all the source pads.

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.
