gpiolib: fix hogs with multiple lines

Browse source

After moving GPIO hog handling into GPIOLIB core, we accidentally stopped
supporting devicetree hog definitions with multiple lines like so:

	hog {
		gpio-hog;
		gpios = <3 0>, <4 GPIO_ACTIVE_LOW>;
		output-high;
		line-name = "foo";
	};

Restore this functionality to fix reported regressions.
