That would also be possible, but I prefer to keep limiting only
the DEBUG_UNCOMPRESS. The idea of DEBUG_LL is that while it's
hardwired to a particular hardware address, it does not actually
access this address unless you specify the 'earlyprintk'
argument on the command line.

We should probably remove the earlyprintk argument from all the
bootargs in the dts files though, because that somewhat defeats
the purpose.
