[Uboot-stm32] [U-BOOT internal][PATCH 3/3] usb: host: dwc2: add trace to have clean usb start

[Patrick Delaunay]

Solve issue for display of usb start command on stm32mp1,
because the carriage return is missing in DWC2 probe.

STM32MP> usb start
starting USB...
USB0:   USB1:   USB EHCI 1.00

after the patch:

STM32MP> usb start
starting USB...
USB0:   USB DWC2
USB1:   USB EHCI 1.00
