mimxrt/mpbthciport: Allow disabling UART flow control for BLE. 

Not all boards or BLE extensions have the flow control signals for BLE
available at suitable pins.  Actually none of the Adafruit extensions
match for flow control.

For consistency with the previous behaviour it is enabled by default.
