[Intel-gfx] [PATCH 1/4] drm/i195: Pass encoder to intel_ddi_enable_pipe_clock()

[Ville Syrjala]

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

Since intel_ddi_enable_pipe_clock() pass pushed down into the
encoder hooks we can pass on the encoder instead of having
to use intel_ddi_get_crtc_encoder().
