hal/generic: introduce rthal_synchronize_irq()
We need a service to wait for interrupts on all CPUs to drain for a
given IRQ line.
rthal_synchronize_irq() provides such service, based on the revised
ipipe_control_irq() routine available with recent I-pipe patches. When
older patches are detected, rthal_synchronize_irq() is a no-op.
