irqchip/gic: Return IRQ_SET_MASK_OK_DONE in the set_affinity method
Moving an SPI around doesn't require any extra work from the rest
of the stack, and specially not for MSI-generated SPIs.
It is then worth returning IRQ_SET_MASK_OK_DONE instead of
IRQ_SET_MASK_OK, and simplify the other irqchips that rely on
this behaviour (GICv2m and Marvell's ODMI controller).
