[PATCH 7/9] drm/i915/wm: Extract skl_print_plane_ddb_changes()

[Ville Syrjala <ville.syrjala@linux.intel.com>]

From: Ville Syrjälä <ville.syrjala@linux.intel.com>

We have skl_print_plane_wm_changes() but the DDB counterpart is
just inline in the main loop. Extract it into a function. We'll
ave a second use for this soon.

The "ddb" part is already parametrized in anticipation of the
second user.
