serial: imx: Fix warning when !CONFIG_SERIAL_IMX_CONSOLE
When CONFIG_SERIAL_IMX_CONSOLE is not selected the following build warnings appear: drivers/tty/serial/imx.c:274:13: warning: 'imx_port_ucrs_save' defined but not used [-Wunused-function] drivers/tty/serial/imx.c:283:13: warning: 'imx_port_ucrs_restore' defined but not used [-Wunused-function] imx_port_ucrs_save() and imx_port_ucrs_restore() are only used when CONFIG_CONSOLE_POLL or CONFIG_SERIAL_IMX_CONSOLE are selected, so protect these functions declaration with a proper ifdef.
