[PATCH v2 07/10] drm/i915/xe3lpd: Add C20 Phy consolidated programming table

[Matt Atwood]

From: Suraj Kandpal <suraj.kandpal at intel.com>

>From DISPLAY_VER() >= 30 C20 PHY consolidated programming table of
DP and eDP been merged and now use the same rates and values. eDP
over TypeC has also been introduced.
Moreover it allows more granular and higher rates. Add new table to
represent this change.
