[PATCH v4 2/8] usb: misc: onboard_dev: add support for non-hub devices

[Javier Carrasco]

Most of the functionality this driver provides can be used by non-hub
devices as well.

To account for the hub-specific code, add a flag to the device data
structure and check its value for hub-specific code.
