In case the selected frequency is higher than the requested one, it is better to send a debug warning rather than an blocking error. In case of such warning, user may need to redefine the clock tree setting at higher level (reducing peripheral's input clocks during init phase).

This is the proposed fix to issue #3849
Description
In case the selected frequency is higher than the requested one, it is
better to send a debug warning rather than an blocking error.
In case of such warning, user may need to redefine the clock tree setting
at higher level (reducing peripheral's input clocks during init phase).
This will avoid to block basic operations that would work anyway with a frequency higher than the requested one.
