I think that this struct shall stay where it was. Moreover, the
clk-provider.h is not the API to be used by other parts of the clock
API.

The clk_fixed_rate shall be accessed via get_rate() only and in IMX6Q
it is available in early SPL (parsed from dts /clocks property - the
24MHz OSC)

Please explain why iMX8MM needs such global export?
