Felipe Balbi 1a356dbc64 usb: dwc3: make glue layers selectable
Glue layers are starting to have separate
requirements. For example, OMAP's glue layer
is starting to use extcon framework which
no one else needs.

In order to make it clear the proper dependencies,
we are now allowing glue layers to be selectable
so that each glue layer can list their own dependencies
without messing with the core IP driver.

Say Y or M here if your system has a Dual Role SuperSpeed
USB controller based on the DesignWare USB3 IP Core.
If you choose to build this driver is a dynamically linked
module, the module will be called dwc3.ko.
