[PATCH] powerpc: Move udbg code to arch/powerpc

Since the udbg code in ppc64 has no ppc32 equivalent, move it straight over into arch/powerpc (and include/asm-powerpc for udbg.h). In time, we probably want to meld the various bits and pieces of 32-bit early debugging code into udbg, but for now only include it on CONFIG_PPC64=y builds. The only change during the move is to standardise the protecting #ifdef/#define in udbg.h, and move its banner comment above the initial #ifdef (which seems to be normal practice). Built and booted on POWER5 LPAR (ARCH=powerpc and ARCH=ppc64). Built for 32bit multiplatform (ARCH=powerpc).
