A fixed-mode output device like a panel will often only inform of its
preferred mode through its EDID. However, the driver will adjust user
specified modes for display through use of a panel-fitter allowing
greater flexibility in upscaling. This is often used by games to set a
low resolution for performance and use the panel fitter to fill the
screen.
v2: Use the presence of the 'scaling mode' connector property as an
indication that a panel fitter is attached to that pipe.

So the kernel removes the device, and the driver processes the first
udev event, and gets no output back from the kernel, so it check
and don't fall over.
This fixes a couple of crashes seen when hotplugging USB devices.

This allows the driver to operate as an output slave.
It adds scan out pixmap, and the capability
checks to make sure they available.

the cirrus driver presents certain challenges, and this is a
workaround, until we can possibly agree some sane interface
for exposing this information.

If the kernel rejects a cursor, cause a fallback, this isn't 100% as
we can lose the initial cursor, but it works fine once wm starts.
