drm/i915: Add MMIO helper for 6 ports with different offsets.
Also new registers can have different mmio offsets
per different lane per port.
v2: Use _PICK as PORT3 instead of creating a new
macro with if per port.
v3: Use _PICK directly on MMIO_PORT6. While MMIO_PORT
isn't flexible enough let's continue with MMIO_PORT6
as we have MMIO_PORT3.
