Add the device node for the Interrupt Controller for External Devices
(INTC-EX) on the Renesas R-Car V4M (R8A779H0) SoC, which serves external
IRQ pins IRQ[0-5].

IRQ2 was tested on the Gray Hawk Single development board using
gpio-keys.  With the default hardware setup, this causes an interrupt
storm, as expected (pin is shared with MD0).

To be queued in renesas-devel for v6.10.

I tested on the Gray Hawk Single board, and it worked correctly like below:
- If SW5-1 on the SW board turned on, the interrupt happened (as strom).
- After that, if the SW5-1 turned off, the interrupt stopped and /proc/interrupts
  showed the interrupt counts.

So,

Best regards,
Yoshihiro Shimoda
