It's not designed to be used as one, but does it work? We've had a
number of boards where this happened in the past, and it was usable for
FEL, or any peripheral really.
If it did work, then this is a regression.
Also, you should explain why this is a good idea: if both can act as a
host, then why should we switch to the HCI controllers?

This is weird to me to have the PHY set in the DTSI for musb, but not
for the USB controllers.
