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 ]

genirq: Set IRQCHIP_SKIP_SET_WAKE for no_irq_chip

If no_irq_chip is used for wake up (e.g. gpio-keys with a simple GPIO
controller), the following warning is printed on resume from s2ram:

WANING: CPU: 0 PID: 1046 at kernel/irq/manage.c:537 irq_set_irq_wake+0x9c/0xf8()
Unbalanced IRQ 113 wake disable

This happens because no_irq_chip does not implement
irq_chip.irq_set_wake(), causing set_irq_wake_real() to return -ENXIO,
and irq_set_irq_wake() to reset the wake_depth to zero.

Set IRQCHIP_SKIP_SET_WAKE to indicate that irq_chip.irq_set_wake() is
not implemented.

Cfr. commit 10a50f1ab5f06c9a ("genirq: Set IRQCHIP_SKIP_SET_WAKE flag
for dummy_irq_chip").
