Clock initialization functionality has ambitious debug messages, which are printed out when failures are triggered during execution: - Separate frequency table lookup functions have the the same output that makes it impossible to understand which function failed and produced the output - PLL decoding routine has a generic debug statement printed, which does not state the actual value failed to be found

Extend the output for both cases with prefixing table lookup functions output with function name, and report the failed value in PLL decoding routine.
