[PATCH 2/3] drm/amd/display: Simplify get_dmif_switch_time_us()

[Christophe JAILLET]

Thanks to the sanity check a few lines above:
    if (!h_total || !v_total || !pix_clk_khz)

and the computation done afterwards on these non 0 values, we know that
'pixels_per_second', 'pixels_per_frame' and 'refresh_rate' are not 0

The code can be simplified accordingly.

NOT compile tested. Because of some BROKEN in KConfig files.
