irqchip: crossbar: Check for premapped crossbar before allocating If irq_of_parse_and_map is executed twice, the same crossbar is mapped to two different GIC interrupts. This is completely undesirable. Instead, check if the requested crossbar event is pre-allocated and provide that GIC mapping back to caller if already allocated.
