genirq: Allow the PM device to originate from irq domain
[ Upstream commit 1f8863bfb5ca500ea1c7669b16b1931ba27fce20 ] As a preparation to moving the reference to the device used for runtime power management, add a new 'dev' field to the irqdomain structure for that exact purpose. The irq_chip_pm_{get,put}() helpers are made aware of the dual location via a new private helper. No functional change intended. Signed-off-by:Marc Zyngier <maz@kernel.org> Reviewed-by:
