Factor out register programming to configure the chip video RX side for reception of video data from DSI or DPI. This is particularly useful in the (e)DP output mode, where the video data can be received from either DPI or DSI. While only the former is supported in (e)DP output mode so far, this patch is added in preparation for addition of the later. There is a change in the order or register programming in case of the DSI-to-DPI mode. The DSI RX side is now programmed and enabled all in one place after the output mode has been configured. Before this change, the DSI RX has been programmed before the output mode has been set and only enabled afterward. The order makes no difference however, since the DSI RX is only enabled at the end either way.

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.
