USB: remove CONFIG_USB_DEVICE_CLASS

This option has been deprecated for many years now, and no userspace
tools use it anymore, so it should be safe to finally remove it.

-          Userspace access to USB devices is granted by device-nodes exported
-          directly from the usbdev in sysfs. Old versions of the driver
-          core and udev needed additional class devices to export device nodes.
-
-          These additional devices are difficult to handle in userspace, if
-          information about USB interfaces must be available. One device
-          contains the device node, the other device contains the interface
-          data. Both devices are at the same level in sysfs (siblings) and one
-          can't access the other. The device node created directly by the
-          usb device is the parent device of the interface and therefore
-          easily accessible from the interface event.
-
-          This option provides backward compatibility for libusb device
-          nodes (lsusb) when usbfs is not used, and the following udev rule
-          doesn't exist:
-            SUBSYSTEM=="usb", ACTION=="add", ENV{DEVTYPE}=="usb_device", \
-            NAME="bus/usb/$env{BUSNUM}/$env{DEVNUM}", MODE="0644"
