gpio: Avoid using an invalid ofnode
Devices do not necessarily have nodes attached to them, since they can be created from platdata. In SPL a devicetree may in fact not exist at all. Check the node before using it. This avoids failure when OF_CHECKS is enabled. Signed-off-by: Simon Glass <sjg@chromium.org> Fixes: 5fc7cf8c8e2 ("gpio: add gpio-hog support") Reviewed-by: Heiko Schocher <hs@denx.de>
