The Renesas RZ/T2H and RZ/N2H SoCs have an Interrupt Control Unit (ICU)
that supports interrupts from external pins IRQ0 to IRQ15, DREQ and SEI.

V2:
 * move reg property after compatible
 * use 100 columns where necessary
 * move SEI comment above if
 * inline declarations of the same type
 * use scoped_guard() in rzt2h_icu_irq_set_type() to avoid keeping the
   guard across the irq_chip_set_type_parent() call
 * align struct irq_chip members initialization
