drm/i915: Move the scheduler feature bits into the purview of the engines
Rather than having the high level ioctl interface guess the underlying
implementation details, having the implementation declare what
capabilities it exports. We define an intel_driver_caps, similar to the
intel_device_info, which instead of trying to describe the HW gives
details on what the driver itself supports. This is then populated by
the engine backend for the new scheduler capability field for use
elsewhere.
v2: Use caps.scheduler for validating CONTEXT_PARAM_SET_PRIORITY (Mika)
One less assumption of engine[RCS] \o/
