Applied to target-arm.next for 6.2, thanks.
If you're connecting the pl011 to the serial backend, you might
also need to implement the CHR_IOCTL_SERIAL_SET_PARAMS handling
so that when the guest sets the baud rate etc it actually works...
CHR_IOCTL_SERIAL_SET_TIOCM and _GET_TIOCM to wire up the flow control
signals will also be helpful I suspect.
