The device-tree node for the PMU clk controller assigns to its parent (i.e. PLL_PPLL) even though this clock currently is set up statically by an init-function.
In order to avoid unexpected failures, a simple implementation of set_rate (which accepts requests, but notifies the caller of the preset frequency in its return value) and get_rate (which always returns the preset frequency) are added.
Note that this is required for the RK808 PMIC to probe successfully on the RK3399-Q7, following the support for the assigned-clocks property.
