Hi All,

The IAX45 block on RZ/Five SoC is almost identical to the IRQC bock found
on the RZ/G2L family of SoCs.

IAX45 performs various interrupt controls including synchronization for the
external interrupts of NMI, IRQ, and GPIOINT and the interrupts of the
built-in peripheral interrupts output by each module. And it notifies the
interrupt to the PLIC.
- Select 32 TINT from 82 GPIOINT.
- Integration of bus error interrupts from system bus.
- Integration of ECC error interrupts from On-chip RAM.
- Indicate interrupt status. (NMI, IRQ, TINT, integrated bus error interrupt
  and integrated ECC error interrupt)
- Setting of interrupt detection method. (NMI, IRQ and TINT)
- All interrupts are masked by INTMASK.
- Mask function for NMI, IRQ and TINT

This patch series adds support for IAX45 in the IRQC driver and enables this
on RZ/Five SoC.

Cheers,
Prabhakar
