drm/i915: Introduce for_each_dbuf_slice_in_mask macro
We quite often need now to iterate only particular dbuf slices
in mask, whether they are active or related to particular crtc.
v2: - Minor code refactoring
v3: - Use enum for max slices instead of macro
Let's make our life a bit easier and use a macro for that.
