[Patch V3 2/9] irqdomain: Use consistent prototype for irq_domain_free_irqs_*

From: Yingjoe Chen <yingjoe.chen at mediatek.com>

When using irq_domain_free_irqs_top() directly in irq_domain_ops, gcc
generate the following warnings:

../drivers/irqchip/irq-gic.c:879:2: warning: initialization from incompatible pointer type [enabled by default]
../drivers/irqchip/irq-gic.c:879:2: warning: (near initialization for 'gic_irq_domain_hierarchy_ops.free') [enabled by default]

Change to use consistent prototype for all irq_domain_free_irqs*

Better to fold this into "irqdomain: Introduce new interfaces to
support hierarchy irqdomains".
