Add the call sites for the various init levels defined by the init system. These call sites are noops if there is no init proceedure registered at a given init level. pre_app_init has been renamed to app_early_init and late_initconfig to app_late_init to better reflect the ordering and intended use of these init levels Change-Id: I71e38d936a97da8fe163f4b7cf0ce6725f1c903e Signed-off-by: Dirk Brandewie <dirk.j.brandewie@intel.com>
