irqchip/renesas-rzt2h: Add software-triggered interrupts support

Browse source

The Renesas RZ/T2H ICU supports software-triggerable interrupts.

Add a dedicated rzt2h_icu_intcpu_chip irq_chip which implements
rzt2h_icu_intcpu_set_irqchip_state() to allow injecting these
interrupts.

Request the INTCPU IRQs when IRQ injection is enabled to report them
when they occur.
