clk: Support for clock parents and rates assigned from device tree
This patch adds helper functions to configure clock parents and rates as specified through 'assigned-clock-parents', 'assigned-clock-rates' DT properties for a clock provider or clock consumer device. The helpers are now being called by the bus code for the platform, I2C and SPI busses, before the driver probing and also in the clock core after registration of a clock provider.
