ARM: dts: microchip: lan966x: Fix the access to the PHYs for pcb8290
The problem is that the MDIO controller can't detect any of the PHYs. The reason is that the lan966x is not pulling high the GPIO 53 that is connected to the PHYs reset GPIO. Without doing this the PHYs are kept in reset. The mdio controller framework has the possibility to control a GPIO to release the reset of the PHYs. So take advantage of this and set line to be high before accessing the PHYs.
