drm/i915/chv: Update Cherryview DPLL changes to support Port D. v2
The additional DPLL registers added to support Port D. Besides, add
some new PHY control and status registers based on B-spec.
v2: Based on Ville review
- Corrected DPIO_PHY_STATUS offset and name.
- Rebase based on upstream change after introduce enum dpio_phy and
enum dpio_channel.
v3: Rebased on top of Antti's 3-pipe prep patch. Note that the new offsets for
the DPLL registers aren't in place yet, so this introduces a slight regression.
But since 3 pipe support isn't fully enabled yet anyaway in -internal this
shouldn't matter too much.
