For a bigjoiner configuration display->crtc_disable() will be called first for the slave CRTCs and then for the master CRTC. However slave CRTCs will be actually disabled only after the master CRTC is disabled (from the encoder disable hooks called with the master CRTC state). Hence the slave PIPEDMCs can be disabled only after the master CRTC is disabled, make this so. intel_encoders_post_pll_disable() must be called only for the master CRTC, as for the other two encoder disable hooks. While at it fix this up as well. This didn't cause a problem, since intel_encoders_post_pll_disable() will call the corresponding hook only for an encoder/connector connected to the given CRTC, however slave CRTCs will have no associated encoder/connector.

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.
