drm/amd/display: Add a missing hook to DCN20 



The struct timing_generator_funcs provides a hook for setting up the
maximum possible vertical dimension of display for OTG, as the panel
supports. DCN10 has a standard function named optc1_set_vtotal_min_max
which all ASICs can use to set the aforementioned hook. Since we did not
set it for DCN20, this commit initializes the set_vtotal_min_max with
the DCN10 function.
