[v7,2/8] Revert "clk: qcom: gcc-sc7280: use new clk_regmap_mux_safe_ops for PCIe pipe clocks"

Commit Message

Dmitry Baryshkov May 21, 2022, 12:53 a.m. UTC

Johan Hovold has pointed out that there are several deficiencies and a
race condition in the regmap_mux_safe ops that were merged. Revert the
commit that switches gcc-sc7280 driver to use regmap_mux_safe.
