[PATCH v4 5/5] usb: host: dwc2: add trace to have clean usb start

[Patrick Delaunay]

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

Before the patch:

STM32MP> usb start
starting USB...
Bus usb-otg at 49000000:    Bus usbh-ehci at 5800d000:   USB EHCI 1.00

after the patch:

STM32MP> usb start
starting USB...
Bus usb-otg at 49000000: USB DWC2
Bus usbh-ehci at 5800d000: USB EHCI 1.00
