[PATCH v6 4/5] clk: qcom: gcc-sc7280: use new clk_regmap_pipe_src_ops for PCIe pipe clocks

[Dmitry Baryshkov <dmitry.baryshkov@linaro.org>]

Use newly defined clk_regmap_pipe_src_ops for PCIe pipe clocks to let
the clock framework automatically park the clock when the clock is
switched off and restore the parent when the clock is switched on.
