drm/i915/dpio: Add per-lane PHY TX register definitons for bxt/glk

Add consistent definitions for the per-lane PHY TX registers
on bxt/glk. The current situation is a slight mess with some
registers having a LN0 define, while others have a parametrized
per-lane definition.

v2: Adjust gvt accordingly
