irqdomain: Introduce irq_domain_create_legacy() API
Introduce irq_domain_create_legacy() API which is functional equivalent to the existing irq_domain_add_legacy(), but takes a pointer to the struct fwnode_handle as a parameter. This is useful for non OF systems. Signed-off-by: Andy Shevchenko <andriy.shevchenko@linux.intel.com> Signed-off-by: Thomas Gleixner <tglx@linutronix.de> Reviewed-by: Rafael J.
