xlat v2: Make get/set attrs functions less verbose
It is useful to have LOG_LEVEL_VERBOSE because it prints the memory map
of each image, but that also means that the change_mem_attributes and
get_mem_attributes functions have verbose prints, and generate a too
long text output that hides other useful information.
As they were mostly there for debug purposes, this patch removes them.
