[PATCH v2 1/3] usb: dwc2: gadget: honor pullup requests in core_connect

[Inochi Amaoto <inochiama@gmail.com>]

The connector ID work initializes the peripheral controller and calls
dwc2_hsotg_core_connect() even when no gadget driver has requested a
connection. After a host-to-device role change, this clears SFTDISCON
and lets the host enumerate an unconfigured gadget.

Check enabled in the connection helper. So the device will keep
disconnect until the controller is ready

Fixes: 510ffaa48eac ("usb: dwc2: Initialize the USB core for peripheral mode")
