drm_sched_init() has a great many parameters and upcoming new
functionality for the scheduler might add even more. Generally, the
great number of parameters reduces readability and has already caused
one missnaming in:
commit 6f1cacf4eba7 ("drm/nouveau: Improve variable name in
nouveau_sched_init()").
Introduce a new struct for the scheduler init parameters and port all
users.

Changes in v3:
- Various formatting requirements.
Changes in v2:
- Point out that the hang-limit is deprecated. (Christian)
- Initialize the structs to 0 at declaration. (Planet Earth)
- Don't set stuff explicitly to 0 / NULL. (Tvrtko)
- Make the structs const where possible. (Boris)
- v3d: Use just 1, universal, function for sched-init. (Maíra)
