Jon Hunter d16dcd3d18 irqdomain: Fix disposal of mappings for interrupt hierarchies
The function irq_create_of_mapping() is used to create an interrupt
mapping. However, depending on whether the irqdomain, to which the
interrupt belongs, is part of a hierarchy, determines whether the
mapping is created via calling irq_domain_alloc_irqs() or
irq_create_mapping().

To dispose of the interrupt mapping, drivers call irq_dispose_mapping().
However, this function does not check to see if the irqdomain is part
of a hierarchy or not and simply assumes that it was mapped via calling
irq_create_mapping() so calls irq_domain_disassociate() to unmap the
interrupt.

Fix this by checking to see if the irqdomain is part of a hierarchy and
if so call irq_domain_free_irqs() to free/unmap the interrupt.
