drm: Handle properties in the core for atomic drivers
The reason behind the original indirection through the helper functions was to allow existing drivers to overwrite how they handle properties. For example when a vendor-specific userspace had expectations that didn't match atomic. That seemed likely, since atomic is standardizing a _lot_ more of the behaviour of a kms driver. But 20 drivers later there's no such need at all. Worse, this forces all drivers to hook up the default behaviour, breaking userspace if they forget to do that. And it forces us to export a bunch of core function just for those helpers. And finally, these helpers are the last places using drm_atomic_legacy_backoff() and the implicit acquire_ctx. This patch here just implements the new behaviour and updates the docs. Follow-up patches will garbage-collect all the dead code. v2: Fixup docs even better! v3: Make it actually work ... v4: Drop the uses_atomic_modeset() checks from the previous patch again, since they're now moved up in the callchain.
