be2bb37f0e 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.

f773c59e89 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.

5276cd4f1d refactor(uart): add support to be able to test LP_UART port
Increase LP_UART_EMPTY_THRESH_DEFAULT value to 4. The original value
could cause the FIFO become empty before filling next data into the FIFO
when the buadrate is high. TX_DONE interrupt would raise before actual
transmission complete in such case.
