[PATCH 2/2] irqchip: crossbar: Fix parent domain resource leak

[Bhargav Joshi]

irq_domain_alloc_irqs_parent() is called in allocate_gic_irq() but
irq_domain_free_irqs_parent() is never called. causing resource leak.

Fix this by calling irq_domain_free_irqs_parent() in
crossbar_domain_free().

Fixes: 783d31863fb82 ("irqchip: crossbar: Convert dra7 crossbar to stacked domains")
