tty.h: new ldisc for TI WiLink ST

Texas Instrument's WiLink7 connectivity devices pack wireless connectivity
technologies like Bluetooth, FM Radio Receiver and Transmitter, GPS and WLAN
into a single die.
The BT, FM and GPS core on the chip are interfaced to application
processors via a single UART.

This line discipline driver allows such different technologies to be used
simultaneous and independent of each other.
