ipq806x: ap3935: Use rgmii-id mode for LAN1

Fix issue with LAN1 interface on ap3935 devices, where the LAN
1interface won't come up after boot unless the bootloader has
initialized the network stack. Use of `fixed-link` in the prior code
kept the driver from clobbering PHY settings, but now that the driver
supports rgmii-id phy-mode, we can just use that.
