genirq/irqdomain: Rename irq_domain::dev to irq_domain:: Pm_dev
irq_domain::dev is a misnomer as it's usually the rule that a device
pointer points to something which is directly related to the instance.
irq_domain::dev can point to some other device for power management to
ensure that this underlying device is not powered down when an interrupt is
allocated.
The upcoming per device MSI domains really require a pointer to the device
which instantiated the irq domain and not to some random other device which
is required for power management down the chain.
Rename irq_domain::dev to irq_domain::pm_dev and fixup the few sites which
use that pointer.
Conversion was done with the help of coccinelle.
