genirq: Add missing SPDX identifiers
Add SPDX identifiers to files
- which contain an explicit license boiler plate or reference
- which do not contain a license reference and were not updated in the
initial SPDX conversion because the license was deduced by the scanners
via EXPORT_SYMBOL_GPL as GPL2.0 only.
[ tglx: Moved adding identifiers from the patch which removes the
references/boilerplate ]
