Support reading edid through aux channel if panel is connected to aux bus. Extend anx7625_aux_dpcd_trans() to implement aux transfer function: 1. panel is populated in devm_of_dp_aux_populate_ep_devices(), so move anx7625_parse_dt() after. 2. Use pm runtime autosuspend since aux transfer function is called multiple times when reading edid. 3. No-op if aux transfer length is 0.

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.
