drm/gud: Enable synchronous flushing by default
gud has a module parameter that controls whether framebuffer flushing
happens synchronously during the commit or asynchronously in a worker.
GNOME before version 3.38 handled all displays in the same rendering loop.
This lead to gud slowing down the refresh rate for a faster monitor. This
has now been fixed so lets change the default.
The plan is to remove async flushing in the future. The code is now
structured in a way that makes it easy to do this.

drm/gud: Use the shadow plane helper
Use the shadow plane helper to take care of mapping the framebuffer for
CPU access. The synchronous flushing is now done inline without the use of
a worker. The async path now uses a shadow buffer to hold framebuffer
changes and it doesn't read the framebuffer behind userspace's back
anymore.

drm/gud: Don't retry a failed framebuffer flush
If a framebuffer flush fails the driver will do one retry by requeing the
worker. Currently the worker is used even for synchronous flushing, but a
later patch will inline it, so this needs to change. Thinking about how to
solve this I came to the conclusion that this retry mechanism was a fix
for a problem that was only in the mind of the developer (me) and not
something that solved a real problem.
So let's remove this for now and revisit later should it become necessary.
gud_add_damage() has now only one caller so it can be inlined.

drm/connector: Rename drm_mode_create_tv_properties
drm_mode_create_tv_properties(), among other things, will create the
"mode" property that stores the analog TV mode that connector is
supposed to output.
However, that property is getting deprecated, so let's rename that
function to mention it's deprecated. We'll introduce a new variant of
that function creating the property superseeding it in a later patch.
