drm/i915/tc: Pass intel_tc_port to internal lane mask/count helpers

Browse Source 
Pass the intel_tc_port pointer instead of intel_digital_port to all lane
mask and count query helpers internal to intel_tc.c, to avoid the
redundant intel_digital_port -> intel_tc_port conversions.

While at it shorten the function names, keeping the intel_tc_port_
prefix only for exported functions and use the mtl_, icl_ prefixes
making it clear which platforms a given query function is specific for.
