[Intel-gfx] [PATCH v3 1/3] drm/i915/icl: replace check for combo phy

[Lucas De Marchi]

These are the only places that assume ports A and B are the ones with
combo phy.  Let's use intel_port_is_combophy() there to make sure
it checks for combo phy ports the same way everywhere.

v2: define for_each_combo_port() helper to check the ports
