Jani Nikula 74770d5d9c drm/i915/display: Limit max joined dotclock on joiner pipes available
Multiplying the max dotclock based on joiner availability on the
platform alone does not take into account the actual pipes (possibly
with some fused) available for joining.

Limit the max joined dotclock based on the actual pipes available for
joining. Add helpers for figuring out the valid primary pipes, based on
having the required joiners and amount of consecutive pipes available.

v2: Check for consecutive pipes available (Ankit)
