arch: arm: dts: k3-am62a7-phyboard-lyra-rdk-u-boot: Disable Ethernet2

Don't initialize Ethernet2 in SPL. We cannot boot from that source anyways
and it throws an error during boot.

This will remove following error message during network boot:

Error: ethernet@8000000port@2 No valid MAC address found.ethernet@8000000port@1
Waiting for PHY auto negotiation to complete....... done
