When boot_mem_alloc() allocates memory up to alignment - 1 number of
bytes may have be skipped to satisfy the required alignment of the
returned pointer. If the skipped bytes, or padding, is large enough,
it's recorded in a list of padding. The list of paddings can be
processed and consumed with boot_mem_foreach_padding(). This allows
sufficiently large paddings to be added to for instance the heap instead
of being wasted.
