[PATCH v2 12/37] clk: fixed-rate: Export driver parts for OF_PLATDATA_INST

Wed Feb 3 17:43:28 CET 2021
We need to allow SoCs to create their own drivers for this so that they
can use their own of-platdata structs. To minimise code duplication,
export the driver operations and the ofdata_to_plat() setup function.
