URL: https://github.com/apache/nuttx/pull/8406

   ## Summary
   
   This is a follow-up to PR #6548, which added UART CTS/RTS support for Tiva 
(TI TM4C12x) microcontrollers.
   
   This follow-up makes it possible, when termios support is enabled with 
`CONFIG_SERIAL_TERMIOS` and CTS/RTS support is enabled with 
`CONFIG_SERIAL_OFLOWCONTROL` and/or `CONFIG_SERIAL_IFLOWCONTROL`, to query 
whether CTS/RTS are on/off at runtime by utilizing ioctl `TCGETS` and to turn 
CTS/RTS on/off at runtime by utilizing ioctl `TCSETS`.
   
   ## Impact
   
   Allow turning CTS/RTS on and off at runtime in the Tiva serial driver.
   
   ## Testing
   
   Custom board.
