Exynos850 and ExynosAuto v9 pinctrl wakeup muxed interrupt

[Krzysztof Kozlowski]

Hi Chanho and Sam,

I am slowly finishing dtschema for Samsung pinctrl drivers [1] and I
noticed that Exynos850 and Auto v9 do not define interrupt in pinctrl
node with: wakeup-interrupt-controller. This is an interrupt muxing
several external wakeup interrupts, e.g. EINT16 - EINT31.

For Exynos5433 this looks like:
https://elixir.bootlin.com/linux/latest/source/arch/arm64/boot/dts/exynos/exynos5433.dtsi#L857

Missing muxed interrupt for Exynos850 and Autov9 might be fine, although
you should see in dmesg error log like:
    "irq number for muxed EINTs not found"

Can you check that your wakeup-interrupt-controller is properly defined
in DTSI? If yes, I will need to include such differences in the dtschema.
