As I understand it imx7d-sdb-sht11.dts uses gpio4 specified in arch/arm/boot/dts/imx7s.dtsi, which has compatible = "fsl,imx7d-gpio", "fsl,imx35-gpio". I don't find a driver compatible fsl,imx7d-gpio, so I guess it is the gpio/gpio-mxc.c driver compatible fsl,imx35-gpio. This driver doesn't use GPIOLIB_IRQCHIP, so I would understand why hwmon/sht15 loads here.
