ARC: IRQ: Do not use hwirq as virq and vice versa
This came up when reviewing code to address missing IRQ affinity setting in AXS103 platform and/or implementing hierarchical IRQ domains - smp_ipi_irq_setup() callers pass hwirq but in turn calls request_percpu_irq() which expects a linux virq. So invoke irq_find_mapping() to do the conversion (also explicitify this in code by renaming the args appropriately) - idu_of_init()/idu_cascade_isr() were similarly using linux virq where hwirq is expected, so do the conversion using irqd_to_hwirq() helper Signed-off-by: Yuriy Kolerov <yuriy.kolerov@synopsys.com> [vgupta: made changelog a bit concise a bit] Signed-off-by: Vineet Gupta <vgupta@synopsys.com>
