[PATCH 2/4] kbuild: spl: Fix parallel build

[Jan Kiszka]

From: Jan Kiszka <jan.kiszka at siemens.com>

The dts dir must exists when running this rule.

That missing dependency broke e.g. "make -j" for the am65x targets.

Fixes: 2f57c95100f2 ("spl: dm: Make it possible for the SPL to pick its own DTB from a FIT")
