serial: imx: Move imx_port_ucrs_save/restore under CONFIG_CONSOLE_POLL
If CONFIG_CONSOLE_POLL is not defined, the following build warning happens: 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] Move imx_port_ucrs_saver/restore under CONFIG_CONSOLE_POLL ifdef block to fix it.
