[PATCH 12/17] arm64: dts: renesas: rzg3s-smarc-som: Guard the ethernet IRQ GPIOs with proper flags

[Claudiu]

From: Claudiu Beznea <claudiu.beznea.uj@xxxxxxxxxxxxxx>

Ethernet IRQ GPIOs are marked as gpio-hog. Thus, these GPIOs are requested
at probe w/o considering if there are other peripherals that needs them.
The Ethernet IRQ GPIOs are shared w/ SDHI2. Selection b/w Ethernet and
SDHI2 is done through a hardware switch. To avoid scenarios where one wants
to boot with SDHI2 support and some SDHI pins are not propertly configured
because of gpio-hog guard Ethernet IRQ GPIO with proper build flag.

Fixes: 932ff0c802c6 ("arm64: dts: renesas: rzg3s-smarc-som: Enable the Ethernet interfaces")
