From: Lucas Stach <l.stach@xxxxxxxxxxxxxx> commit 427627a23c3e86e31113f9db9bfdca41698a0ee5 upstream. Since 699cc4dfd140 (tty: serial: imx: add imx earlycon driver), the earlycon part of imx serial is a separate driver and isn't necessarily enabled anymore when the console is enabled. This causes users to loose the earlycon functionality when upgrading their kenrel configuration via oldconfig. Enable earlycon by default when IMX_SERIAL_CONSOLE is enabled.
