clk: clk_stm32: Add .set_rate callback

Browse Source 
Since 'commit f4fcba5c5b ("clk: implement clk_set_defaults()")'
STM32F4 family board can't boot.

Above patch calls clk_set_rate() for all nodes with assigned-clock-rates
property. Clock driver for STM32F family doesn't implement .set_rate
callback which make clk_set_defaults() exit on error and prevent board
to boot.
