The only useful thing about CONFIG_DEFAULT_CONSOLE and ${console} env is
to propagate earlycon argument to kernel. As console kernel argument is
already set via chosen/stdout in DTS.

Setting earlycon directly to ${bootargs} env does not work as basically
all distribution scripts set/overwrite ${bootargs} on their own.

So we need to store earlycon argument into some other uboot env and then
teach these distribution scripts to append that new uboot env into their
bootargs...

Or is there any other way?
