clk: qcom: gcc-qdu1000: Fix gcc_pcie_0_pipe_clk_src clock handling

Fix the gcc pcie pipe clock handling as per the clk_regmap_phy_mux_ops
implementation to let the clock framework automatically park the clock
at XO when the clock is switched off and restore the parent when the
clock is switched on.

Fixes: 1c9efb0bc040 ("clk: qcom: Add QDU1000 and QRU1000 GCC support")
