David Sidrane b556d668f8 RCInput:Add Support for RX-TX SWAP using onewire
A board can optionaly define RC_SERIAL_SWAP_USING_SINGLEWIRE
   If the board is wired board with TX to the input (Swapped) and
   the SoC does not support U[S]ART level RX-TX swapping to allow
   useing onewire to do the swap if and only if:

     RC_SERIAL_SWAP_USING_SINGLEWIRE   is defined
     RC_SERIAL_SWAP_RXTX               is defined
     TIOCSSWAP                         is defined and retuns !OK
     TIOCSSINGLEWIRE                   is defined
