[PATCH 03/19] drm/i915: Clean up WRPLL/SPLL #defines

[Imre Deak <imre.deak@intel.com>]

From: Daniel Vetter <daniel.vetter@ffwll.ch>

Luckily the bit definitions match, but it's still confusing
to use one when handling the other. So sprinkle some OCD over
the #defines to make them match and use the right version in
each place.

Maybe we should unify these definitions completely, but that
can always be done sometime in the future.
