Adjust the HSW+ transcoder state readout to just read through all the possible transcoders for the pipe, and stuff the results in a bitmask. We can conveniently cross check the bitmask for invalid combinations of enabled transcoders, and later we can easily extend the bitmask readout to handle the bigjoiner case. One slight change in behaviour is that we no longer read out the AONOFF->force_pfit.pfit bit for all the enabled "panel transcoders". But having more than one enabled would anyway be illegal so no big loss. Also the AONOFF selection should only ever be used on HSW, which only has the EDP transcoder an no DSI transcoders.

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.
