arm64: dts: renesas: white-hawk-single: Improve Ethernet TSN description

Browse Source 
- Add the missing "ethernet3" alias for the Ethernet TSN port, so
    U-Boot will fill its local-mac-address property based on the
    "eth3addr" environment variable (if set), avoiding a random MAC
    address being assigned by the OS,
  - Rename the numerical Ethernet PHY label to "tsn0_phy", to avoid
    future conflicts, and for consistency with the "avbN_phy" labels.
