This patch is the preparation for SM8150 support. This new SoC depending on the particular pin can have different numbers for the same function. For example "rgmii" function for GPIO4 has id=2 while for GPIO59 it has id=1. So, to support this type of SoCs, get_function_mux() callback needs to know for which pin the function is requested.
