de878df848 fix(uart): Avoid division by zero error when calling uart_get_baudrate 
If uart_driver_install is not called before uart_get_baudrate,
the UART port may not be ready. In such cases, the register values
cannot be read out, leading to a division by zero error in uart_ll_get_baudrate.
This commit adds a check to ensure the UART port is enabled before
attempting to read its registers.

8974851c8a fix(uart): tx write bytes fails to use non-default tx fifo empty threshold 
Users may see tx write bytes fails to feed data into tx fifo in time
even if the tx fifo empty threshold has been set to a large value.
