Revert "ARM: Make low-level printk work"
This reverts commit 63d454ab530bb3ab5412aabd6be6ee8cd340888e.
Per Andy's request,
Andy's rational:
"I don't think that makes any sense any more and should be removed,
unless there's some case on Android side that really needs it. Vanilla
has better DEBUG_LL support now since 2005 when that patch was
introduced and the Android kernels will inherit it. I've reverted it in
my tree since we commonly need DEBUG_LL on (but we don't need printascii
garbling all our logging as if there was an echo in there).
...[It] basically forces all printk output down printascii() which is
not what we want.

On your commandline will get you going [without this]"
