When upstreamed the SC7280 DP controllers where described as one being
DP and one eDP, but they can infact both be DP or eDP.

Extend the list of DP controllers to cover both instances, and rely on
the newly introduced mechanism for selecting which mode they should
operate in.

Move qcom,sc7280-edp to a dedicated list, to ensure existing DeviceTree
will continue to select eDP.
