[PATCH v3 1/8] usb: ulpi: move setting of ulpi->dev parent up in ulpi_register()

[Tal Shorer <tal.shorer@gmail.com>]

Once ulpi operations use the parent device directly, this will be
needed during the operations used in ulpi_register() itself, so set
the parent field before calling any ulpi operations.
