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

From: Randy Dunlap
Date: Sat Dec 27 2025 - 15:25:59 EST


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.
