[Intel-gfx] [PATCH 03/25] drm/i915/guc: Take engine PM when a context is pinned with GuC submission

Taking a PM reference to prevent intel_gt_wait_for_idle from short circuiting while any user context has scheduling enabled. Returning GT idle when it is not can cause all sorts of issues throughout the stack. v2: (Daniel Vetter) - Add might_lock annotations to pin / unpin function v3: (CI)
