Instead of giving zero support of uncompress debug for multiplatform
build, the patch turns uncompress debug into one part of DEBUG_LL
support.  When DEBUG_LL is turned on for a particular platform,
uncompress debug works too for that platform.

It reuses the platform DEBUG_LL macros by creating a simple
arch/arm/boot/compressed/debug.S with CONFIG_DEBUG_LL_INCLUDE
included there, and implements a generic putc() using those macros.

Ok, I've applied this on the previso that _no one_ in future whinges if
the debug infrastructure doesn't quite meet their expectation.  The
debug infrastructure remains first and foremost that: a simple debug
infrastructure suitable for use in the early assembly and the like.

That is its primary concern and trumps any requirements from consoles,
early printk, decompressor output, and the like.

... and now I've dropped the two patches because it causes build failures
for all OMAP and PXA platforms.
