common: Move bootm_decomp_image() to image.c (as image_decomp())

Browse Source 
Upcoming patches want to add decompression to use cases that are no
longer directly related to booting. It makes sense to retain a single
decompression routine, but it should no longer be in bootm.c (which is
not compiled for all configurations). This patch moves
bootm_decomp_image() to image.c and renames it to image_decomp() in
preparation of those upcoming patches.
