[Intel-gfx] [PATCH 3/7] drm/i915/icl: Add register defs for voltage swing sequences for MG PHY DDI

From: Manasi Navare <manasi.d.navare at intel.com>

On Icelake platform, MG PHY is used when operating in DP alternate
mode or the legacy HDMI or DP modes. DDI Ports C, D, E, F are MG PHY
DDI ports on ICL.

This patch adds the necessary voltage swing programming related
register definitions and macros for MG PHY DDI ports.

v4 (from Paulo):
* Use _PORT instead of _PICK
* Change some mask names to our current coding standards
* Stay under 80 columns
v3:
* Rebase on new revision of patches
v2:
* Remove whitespaces in the #defines (Paulo)
