Subject: [PATCH -next] usb: build drivers/usb/common/ when USB_SUPPORT is set

From: Randy Dunlap <rdunlap@...radead.org>

PHY drivers can use ULPI interfaces when CONFIG_USB (which is host side
support) is not enabled, so also build drivers/usb/ when CONFIG_USB_SUPPORT
is enabled so that drivers/usb/common/ is built.
