[PATCH v5 9/9] drm/i915: Address broxton phy registers based on phy and channel number

[Ander Conselvan de Oliveira <ander.conselvan.de.oliveira@intel.com>]

The port registers related to the phys in broxton map to different
channels and specific phys. Make that mapping explicit.

v2: Pass enum dpio_phy to macros instead of mmio base. (Imre)

v3: Fix typo in macros. (Imre)

v4: Also change variables from u32 to enum dpio_phy. (Imre)
    Remove leftovers from previous version. (Imre)

v5: Actually git add the changes.
