Paul Mundt 45bbaae0dc ARM: mach-shmobile: Split out entry-macros in to GIC and INTC variants.
Presently the entry macros are all globbed together, this simply splits
them out in to their insular variants. Future work such as the GIC
generalization will replace some of these and tidy the abstraction up
further.
