ARM: dts: BCM53573: Fix Ethernet info for Luxul devices

Browse source 
Both Luxul's XAP devices (XAP-810 and XAP-1440) are access points that
use a non-default design. They don't include switch but have a single
Ethernet port and BCM54210E PHY connected to the Ethernet controller's
MDIO bus.

Support for those devices regressed due to two changes:

1. Describing MDIO bus with switch
After commit 9fb90ae6ca ("ARM: dts: BCM53573: Describe on-SoC BCM53125
rev 4 switch") Linux stopped probing for MDIO devices.

2. Dropping hardcoded BCM54210E delays
In commit fea7fda7f5 ("net: phy: broadcom: Fix RGMII delays
configuration for BCM54210E") support for other PHY modes was added but
that requires a proper "phy-mode" value in DT.

Both above changes are correct (they don't need to be reverted or
anything) but they need this fix for DT data to be correct and for Linux
to work properly.

Fixes: 9fb90ae6ca ("ARM: dts: BCM53573: Describe on-SoC BCM53125 rev 4 switch")
