clk: qcom: regmap-mux: fix parent clock lookup
The function mux_get_parent() uses qcom_find_src_index() to find the
parent clock index, which is incorrect: qcom_find_src_index() uses src
enum for the lookup, while mux_get_parent() should use cfg field (which
corresponds to the register value). Add qcom_find_cfg_index() function
doing this kind of lookup and use it for mux parent lookup.
Fixes: df964016490b ("clk: qcom: add parent map for regmap mux")
