usb: xhci: Add timeout argument in address_device USB HCD callback
- The HCD address_device callback now accepts a user-defined timeout value
in milliseconds, providing better control over command execution times.
- The default timeout value for the address_device command has been set
to 5000 ms, aligning with the USB 3.2 specification. However, this
timeout can be adjusted as needed.
- The xhci_setup_device function has been updated to accept the timeout
value, allowing it to specify the maximum wait time for the command
operation to complete.
- The hub driver has also been updated to accommodate the newly added
timeout parameter during the SET_ADDRESS request.
