This requires the following: * Gathering all KPU profile related data into a single adapter struct. * Converting the built-in MKEX definition to a structured one to streamline the MKEX loading. * Convert LT default register configuration into a structure which may later on be customized. * Add a single point for KPU profile loading, currently using only built-in profile.
