drm/i915/cnl: Add allowed DP rates for Cannonlake.

"Frequencies over 5.4 GHz only supported on certain
DDI ports and SKUs, and requires Vccio >= 0.95V."

More specifically, for current CNL SKUs available
(CNL-U and CNL-Y) we have:

DDI A - 5.4G eDP
DDI B - 8.1G DP
DDI C - 8.1G DP
DDI D - 5.4G DP

v2: Rebase on top of source_rates changes.
v3: Address the max 5.4 x 8.1 per DDI and also consider vccio.
