irqchip/riscv-intc: Add missing free() callback in riscv_intc_domain_ops
The irq_domain_free_irqs() helper requires that the irq_domain_ops->free
callback is implemented. Otherwise, the kernel reports the warning message
"NULL pointer, cannot free irq" when irq_dispose_mapping() is invoked to
release the per-HART local interrupts.
Set irq_domain_ops->free to irq_domain_free_irqs_top() to cure that.
