Nicholas Kazlauskas bc92c06525 drm/amd/display: Allow commits with no planes active
[Why]
Many userspace applications (and IGT) seem to expect that most drivers
can keep a CRTC active and enabled if there are no primary or overlay
planes.

DC is setup to handle this but only in the case where there are
absolutely no planes on the CRTC - no primary, cursor, or overlay.

[How]
Add a check to reject commits that have cursor planes enabled and
nothing else on CRTCs since we can't handle that. The new helper
does_crtc_have_active_cursor is used for this.

In atomic commit tail, we need to let DC know that there are zero
planes enabled when doing stream updates to let it disable and blank
pipes as appropriate.

README

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.
