Mark Salter f84f1f462b C6X: remove dependence on legacy IRQs
The core priority PIC code uses legacy irq support to facilitate direct
mapping of core hw interrupt numbers to linux interrupt numbers. This
patch removes the legacy irq usage and replaces it with a generic linear
mapping.

Grant Likely a699e4e49e irq: Kill pointless irqd_to_hw export
It makes no sense to export this trivial function.  Make it a static inline
instead.

This patch also drops virq_to_hw from arch/c6x since it is unused by that
architecture.

v2: Move irq_hw_number_t into types.h to fix ARM build failure

Mark Salter 0bd761e1b6 irq_domain/c6x: Convert c6x to use generic irq_domain support.
The C6X IRQ support was copied almost verbatim from the PowerPC virtual IRQ
code. The PowerPC code was used as the basis for generic irq_domain support,
so this patch mostly copies what what done to arch/powerpc by Grant Likely
in his irq_domain patch series.
