Dmitry Baryshkov 17edb38e76 clk: qcom: regmap-mux: fix parent clock lookup ...

commit 9a61f813fcc8d56d85fcf9ca6119cf2b5ac91dd5 upstream.

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: df96401649 ("clk: qcom: add parent map for regmap mux")
