This patch removes the depends on USB from all config symbols in

This looks almost right. The only problem I see is in
drivers/usb/core/Kconfig. The USB_OTG_WHITELIST and
USB_OTG_BLACKLIST_HUB symbols don't have to depend on USB or USB_OTG,
because they can be set if EXPERT is enabled.
To avoid these issues, I think the best approach is to move all the
USB_OTG* entries over to drivers/usb/otg/Kconfig, where by rights they
should have been all along.
Felipe, do you agree?
