drm/i915/dp_link_caps: Add support for link rate, lane count iteration orders

Browse source

Add support for iterating configurations in either link rate/lane count
or lane count/link rate order. Both orders are required for DP SST
connector types: the former for computing the connector state during a
modeset, and the latter for selecting a fallback configuration after a
link training failure.
