serdev: Split and export serdev_acpi_get_uart_resource()
The same as for I²C Serial Bus resource split and export serdev_acpi_get_uart_resource(). We have already a few users one of which is converted here. Rationale of this is to consolidate parsing UART Serial Bus resource in one place as it's done, e.g., for I²C Serial Bus.
