[PATCH 2/4] drm/i915: Move engine->needs_cmd_parser to engine->flags

[Tvrtko Ursulin <tursulin@ursulin.net>]

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

Will be adding a new per-engine flags shortly so it makes sense
to consolidate.

v2: Keep the original code flow in intel_engine_cleanup_cmd_parser.
