usb: print number of skipped OTG controllers when scanning
I often get confused by running usb and wondering why devices behind
unconfigured OTG controllers are not enumerated. Improve the user
experience by printing a message when doing a USB scan while some OTG
controllers are not yet configured (i.e. the otg.mode device parameter
hasn't been set to "peripheral" or "host").
