For the adv7604 the hotplug detect pin is controlled through gpio pins from the SoC, but the adv7611 and adv7612 control the hotplug detect pin themselves. But the driver had no support for this, so the HPD was always high, even when changing the EDID. Add proper support for this to the driver. Tested with an adv7612.

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.
