Dom Cobley ccbf1b9ad8 drm/vc4_hdmi: Allow hotplug detect to be forced
See: https://forum.libreelec.tv/thread/24783-tv-avr-turns-back-on-right-after-turning-them-off

While the kernel provides a :D flag for assuming device is connected,
it doesn't stop this function from being called and generating a cec_phys_addr_invalidate
message when hotplug is deasserted.

That message provokes a flurry of CEC messages which for many users results in the TV
switching back on again and it's very hard to get it to stay switched off.

It seems to only occur with an AVR and TV connected but has been observed across a
number of manufacturers.

The issue started with https://github.com/raspberrypi/linux/pull/4371
and this provides an optional way of getting back the old behaviour

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.
