Otherwise printch et al. and printk with earlyprintk and keep_bootcon
becomes unfunctional when the clk framework disables all unused clocks.
Why don't you use the regular console? Letting the clock framework
disable the clocks was pretty much intentional.
I don't question that disabling unused clocks is sensible. But usually
if you enable DEBUG_LL you want to use it even after the clock framework
disabled all (apparently) unused clocks. And in my case the regular
console didn't work yet and so I relied on earlyprintk.
Even if the problem proved to be the result of my stupidity this patch
asserts that earlyprintk just works as it should be for debug aids.
