Subject: [PATCH 1/4] serial: imx: change SERIAL_IMX_CONSOLE to bool

SERIAL_IMX_CONSOLE is a build option for the imx driver (SERIAL_IMX).
It does not build a separate console driver file, so it can't be built
as a module since it isn't built at all.

Change the Kconfig symbol from tristate to bool and update the help
text accordingly.

Fixes: 0db4f9b91c86 ("tty: serial: imx: enable imx serial console port as module")
