[PATCH 16/23] drm/amd/display: Add a missing hook to DCN20

[Qingqing Zhuo]

From: Rodrigo Siqueira <Rodrigo.Siqueira at amd.com>

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.
