net: phy: support 'active-high' property for PHY LEDs
In addition to 'active-low' and 'inactive-high-impedance' also support 'active-high' property for PHY LED pin configuration. As only either 'active-high' or 'active-low' can be set at the same time, WARN and return an error in case both are set.
