drm/i915/tc: Pass pin assignment value around using the pin assignment enum
Pass around the pin assignment value via the corresponding enum instead
of a plain integer.
While at it rename intel_tc_port_get_pin_assignment_mask() to
intel_tc_port_get_pin_assignment(), since the value returned is not a
mask.
