drm/i915/dp_mst: Use link caps for non-DSC config selection

Browse source

Use the link caps helper to select the maximum MST link configuration
for non-DSC computation, instead of using the separate max rate and lane
count limits, which may not form a valid configuration after individual
configs are disabled by fallback.

This is a step towards unifying configuration selection and iteration
across connector types and between compute and fallback paths.

In some cases all configurations should be considered, as noted in the
code comment; for now keep the existing behavior of selecting the
maximum bandwidth configuration as determined by the MST connector's BW
config iteration order.
