Say Y here if you want to support discrete onboard USB devices
that don't require an additional control bus for initialization,
but need some non-trivial form of initialization, such as
enabling a power regulator. An example for such device is the
Realtek RTS5411 hub.
This driver can be used as a module but its state (module vs
builtin) must match the state of the USB subsystem. Enabling
this config will enable the driver and it will automatically
match the state of the USB subsystem. If this driver is a
module it will be called onboard_usb_dev.
