Benjamin Herrenschmidt d4d7a59a7a ppc/xics: Split ICS into ics-base and ics class
The existing implementation remains same and ics-base is introduced. The
type name "ics" is retained, and all the related functions renamed as
ics_simple_*

This will allow different implementations for the source controllers
such as the MSI support of PHB3 on Power8 which uses in-memory state
tables for example.
