66030feab5 fix(uart): lp uart rx iomux pin was not working as expected 
Introduced in 8818157e42
The workaround in the commit routes the signal to LP GPIO matrix first.
When uses LP IOMUX pin as UART RX, the signal did not bypass the matrix,
which caused the issue.

This commit adds rtc_gpio_iomux_input and rtc_gpio_iomux_output APIs
to align with existing GPIO driver APIs.

e801bde973 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.
