sc16is7xx: expose RTS inversion in RS-485 mode
Hardware is capable of inverting RTS signal when working in RS-485 mode. Expose this functionality to user space. Relay on a matching combination of standard flags (SER_RS485_RTS_ON_SEND and SER_RS485_RTS_AFTER_SEND) to detect when user space is requesting inverted RTS mode.
