apm821xx: clean up gpio-hogs
convert the usb and both sata port power related gpio-hogs to what they really are: fixed-regulators. The ethernet phy-reset gpio-hog is replaced by a proper upstream (4.15+) reset-gpios property in the mdio-node. So this will work eventually. Signed-off-by: Christian Lamparter <chunkeey@gmail.com>
