drm/doc/rfc: Mark drm_scheduler as completed

Current drm-xe-next doesn't have any drm/scheduler patch that is not
already accepted in drm-misc-next. This completed this goal with
the consensus of how the drm/scheduler fits to the fw scheduling and
the relationship between drm_gpu_scheduler and drm_sched_entity.

Xe Pre-Merge Goals - Work-in-Progress
=======================================
Drm_scheduler
-------------
Xe primarily uses Firmware based scheduling (GuC FW). However, it will use
drm_scheduler as the scheduler frontend for userspace submission in order to
resolve syncobj and dma-buf implicit sync dependencies. However, drm_scheduler is
not yet prepared to handle the 1-to-1 relationship between drm_gpu_scheduler and
drm_sched_entity.
Deeper changes to drm_scheduler should *not* be required to get Xe accepted, but
some consensus needs to be reached between Xe and other community drivers that
could also benefit from this work, for coupling FW based/assisted submission such
as the ARMs new Mali GPU driver, and others.
As a key measurable result, the patch series introducing Xe itself shall not
depend on any other patch touching drm_scheduler itself that was not yet merged
through drm-misc. This, by itself, already includes the reach of an agreement for
uniform 1 to 1 relationship implementation / usage across drivers.
