From: Marcel Ziswiler <marcel.ziswiler at toradex.com>
This fixes the following crash when run on a Colibri iMX7S aka solo:
Colibri iMX7 # usb start
starting USB...
Bus usb at 30b10000: USB EHCI 1.00
Bus usb at 30b20000:
The i.MX 7Solo has only one single USB OTG1 but no USB host port. Trying
to initialize the nonexisting port just crashes.
While at it also drop board_usb_phy_mode() which is also no longer used
in the driver model age.
