drm/display/dp: Export fn to calculate link symbol cycles
Unify the function to calculate the link symbol cycles for both dsc and
non-dsc case and export the function so that it can be used in the
respective platform display drivers for other calculations.
v2: unify the fn for both dsc and non-dsc case (Imre)
v3: rename drm_dp_link_symbol_cycles to drm_dp_link_data_symbol_cycles
retain slice_eoc_cycles as is (Imre)
v4: Expose only drm_dp_link_symbol_cycles() (Imre)
v6: Add slice pixels which was removed unknowingly (Vinod)
