clk: qcom: Introduce parent_map tables
In the current parent mapping code, we can get duplicate or inconsistent indexes, which leads to discrepancy between the number of elements in the array and the number of parents. Until now, this was solved with some reordering but this is not always possible. This patch introduces index tables that are used to define the relations between the PLL source and the hardware mux configuration value. To accomplish this, here we do the following: - Define a parent_map struct to map the relations between PLL source index and register configuration value. - Add a qcom_find_src_index() function for finding the index of a clock matching the specific PLL configuration. - Update the {set,get}_parent RCG functions use the newly introduced parent_map struct. - Convert all existing drivers to the new parent_map tables.
