kbuild: refactor Makefile and spl/Makefile more
This commit refactors rules of directory descending and defines u-boot-dirs and u-boot-all-dirs. (We will need u-boot-all-dirs when using scripts/Makefile.clean) Additionally, rename LIBS-y to libs-y. Signed-off-by: Masahiro Yamada <yamada.m@jp.panasonic.com>
