termios: Add TERMIOS_IRQ_SERVER_DRIVEN
Add a new interrupt server driven Termios mode (TERMIOS_IRQ_DRIVEN).
This mode is identical to the interrupt driven mode except that a mutex
is used for device level locking. The intended use case for this mode
are device drivers that use the interrupt server, e.g. SPI or I2C
connected devices.
Update #2839.
