Okay, will update.

The node names come directly from the included talos.dtsi, where they
are defined as usb_1_hsphy & usb_hsphy_2.
To avoid breaking inherited definitions, we kept the same labels
in our board DTS.
However, I will reorder the nodes so they appear in a logical and
consistent sequence.
