siemens: factoryset: use correct config for soc specific implementation

Adding the capricorn board family some parts diverge from draco family.
The switches used were not pertinent and need to be enhanced for each new
board of the capricorn family. Replace them through the SOC name 'AM33XX'
and 'IMX8'.
