This is necessary for the upcoming STM32MP1 based board called Stinger96 IoT-Box. On that board, a bluetooth chip is connected to one of the UART controller but the CTS/RTS lines got swapped mistakenly. So in order to workaround that hardware bug and also to support the usecase of using only Tx/Rx pins, this patchset adds software flow control support. This patchset has been validated w/ Stinger96 IoT-Box connected to Murata WiFi-BT combo chip.
