serial: imx: Fix warning when building 'allmodconfig'
When CONFIG_SERIAL_IMX_CONSOLE=n and CONFIG_CONSOLE_POLL=y we get the following build warning: drivers/tty/serial/imx.c:306:13: warning: 'imx_port_ucrs_save' defined but not used [-Wunused-function] drivers/tty/serial/imx.c:315:13: warning: 'imx_port_ucrs_restore' defined but not used [-Wunused-function] imx_port_ucrs_save/restore are only used under CONFIG_SERIAL_IMX_CONSOLE, so their definitions should be also be protected only by CONFIG_SERIAL_IMX_CONSOLE. This was detected when building 'allmodconfig'.
