Ville Syrjälä e12d6218fd drm/i915: Reduce bigjoiner special casing
Try to make bigjoiner pipes less special.

The main things here are that each pipe now does full
clock computation/readout with its own shared_dpll reference.
Also every pipe's cpu_transcoder always points correctly
at the master transcoder.

Due to the above changes state readout is now complete
and all the related hacks can go away. The actual modeset
sequence code is still a mess, but I think in order to clean
that up properly we're probably going to have to redesign
the modeset logic to treat transcoders vs. pipes separately.
That is going to require significant amounts of work.

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.
