drm/i915/dp: Use link caps for eDP DSC config selection

Browse source

Use the link caps helper to select the maximum eDP link configuration
for 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.

The state computation should likely consider all allowed configurations,
as noted in the code comment; for now keep the existing eDP DSC behavior
of selecting the maximum configuration determined by the eDP connector
rate / lane config iteration order.
