[Qemu-ppc] [PATCH v4 6/9] ppc/xics: Split ICS into ics-base and ics class

[Nikunj A Dadhania]

From: Benjamin Herrenschmidt <address@hidden>

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.
