This is a code factoring to have the Python bindings in one location, and all the ports use those same bindings. For all ports except the two listed below there is no functional change. The nrf port has UART.sendbreak() removed, but this method previously did nothing. The zephyr port has the following methods added: - UART.init(): supports setting timeout and timeout_char. - UART.deinit(): does nothing, just returns None. - UART.flush(): raises OSError(EINVAL) because it's not implemented. - UART.any() and UART.txdone(): raise NotImplementedError.
