The SCP (System Control Processor) or what we call STM (Stand-by
MPU) is integrated in LD4, Pro4, sLD8, LD6b, LD11, and LD20.
For these SoCs, show the information if STM is enabled.

The current implementation has ugly switch statements here and there,
and duplicates similar code. Rework it using table lookups for SoC
data and reduce code duplication.
