kbuild: determine base DTB by suffix
When using the -dtbs syntax, you need to list the base first, as
follows:
foo-dtbs := foo_base.dtb foo_overlay1.dtbo foo_overlay2.dtbo
dtb-y := foo.dtb
You cannot do this arrangement:
foo-dtbs := foo_overlay1.dtbo foo_overlay2.dtbo foo_base.dtb
This restriction comes from $(firstword ...) in the current
implementation, but it is unneeded to rely on the order in the
-dtbs syntax.
Instead, you can simply determine the base by the suffix because
the base (*.dtb) and overlays (*.dtbo) use different suffixes.
