Revert "ARM: Make low-level printk work"

Browse Source 
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.

        earlyprintk=1 earlycon=ttyO2,115200n8

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