genirq: Provide generic_handle_domain_irq_safe().

commit 509853f9e1e7b ("genirq: Provide generic_handle_irq_safe()")
addressed the problem of demultiplexing interrupt handlers which are force
threaded on PREEMPT_RT enabled kernels which means that the demultiplexed
handler is invoked with interrupts enabled which triggers a lockdep
warning due to a non-irq safe lock acquisition.

The same problem exists for the irq domain based interrupt handling via
generic_handle_domain_irq() which has been reported against the AMD
pin-ctrl driver.

Provide generic_handle_domain_irq_safe() which can used from any context.
