[PATCH v3 04/13] drm/msm/hdmi: drop clock frequency assignment

From: Dmitry Baryshkov
Date: Sat Jun 22 2024 - 18:03:02 EST


The only clock which has frequency being set through hpd_freqs is the
"core" aka MDSS_HDMI_CLK clock. It always has the specified frequency,
so we can drop corresponding clk_set_rate() call together with the
hpd_freq infrastructure.
