[PATCH] arm64: dts: renesas: r8a779h0: Add INTC-EX node

[Geert Uytterhoeven]

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].

Signed-off-by: Geert Uytterhoeven <geert+renesas at glider.be>
---
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.
