[PATCH 24/32] Makefile: Use empty SPL_ and SPL_TPL_ vars

[Simon Glass]

Now that we include an auto.conf file specific to the phase being built
we can make these variables empty.

With this done, we can also remove them from U-Boot entirely, dropping
them from all Makefiles. That is left for a future clean-up since we
cannot apply this series until CONFIG migration is complete.
