[RFC 6/8] drm/i915: Make some recently added vfuncs use full scheduling attribute

From: Tvrtko Ursulin <tvrtko.ursulin@intel.com>

Code added in 71ed60112d5d ("drm/i915: Add kick_backend function to
i915_sched_engine") and ee242ca704d3 ("drm/i915/guc: Implement GuC
priority management") introduced some scheduling related vfuncs which
take integer request priority as argument.

Make them instead take struct i915_sched_attr, which is the type
encapsulating this information, so it probably aligns with the design
better. It definitely enables extending the set of scheduling attributes.
