serial: uapi: Add support for bus termination
The Siemens IOT2040 comes with a RS485 interface that allows to enable or disable bus termination via software. Add a bit to the flags field of serial_rs485 that applications can set in order to request this feature from the hardware. This seems generic enough to add it for everyone. Existing driver will simply ignore it when set.
