init: Add init system calls to micro and nano kernel init

Browse source 
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
