PR Description

Add revision-specific DTS files layered on top of sc598-som.dtsi
to support Rev D and E.

Fix errors in the existing GPIO expanders by correcting
GPIO definitions and polarities so they match the hardware.

Currently, these GPIO hogs are defined as GPIO_ACTIVE_HIGH in the device tree. This patch updates them to GPIO_ACTIVE_LOW to accurately reflect the hardware polarity. Fixes: a5d4be9 ("arm64: dts: adi: sc598: add device tree") Signed-off-by: Ozan Durgut <ozan.durgut@analog.com>
