cnss2: Support USB SSR and disconnect scenarios
For USB devices, irrecoverable scenarios in firmware
can lead to USB bus disconnect. In USB disconnect, the
interface and dev structures passed by USB sub system
are freed and are no longer valid. The current
implementation is PCIe specific and assumes dev struct
being present and valid always. The clean way to handle
this for HL(USB/SDIO) is to call pld_usb_remove in
disconnect and pld_usb_probe in re-connect after a recovery
