add boot_get_loadables() to load listed images
Added a trimmed down instance of boot_get_<thing>() to satisfy the minimum requierments of the added feature. The function follows the normal patterns set by other boot_get<thing>'s, which should make it a bit easier to combine them all together into one boot_get_image() function in a later refactor. Documentation for the new function can be found in source: include/image.h Signed-off-by: Karl Apsite <Karl.Apsite@dornerworks.com> Reviewed-by: Simon Glass <sjg@chromium.org>
