[ARM] S3C24A0: Debug macro definitions Add the necessary debug macros for the S3C24A0 to enable kernel debugging, and fix a bug with selecting the wrong default debug implementation from the base include. Signed-off-by: Ben Dooks <ben-linux@fluff.org>

arm: return both physical and virtual addresses from addruart Rather than checking the MMU status in every instance of addruart, do it once in kernel/debug.S, and change the existing addruart macros to return both physical and virtual addresses. The main debug code can then select the appropriate address to use. This will also allow us to retreive the address of a uart for the MMU state that we're not current in. Updated with fixes for OMAP from Jason Wang <jason77.wang@gmail.com> and Tony Lindgren <tony@atomide.com>, and fix for versatile express from Lorenzo Pieralisi <lorenzo.pieralisi@arm.com>.
