init: add pure_core_init level

Browse source 
There are devices that need are part of the architecture core the need
to be initialized prior to devices that are integrated around a core
to make up a complete SOC. Namely the interrupt controller in the SOC
must be configured in order to allow the integrated IP blocks drivers
to initialize correctly.
