%.dtb: prepare3 prepare


because we need to make sure KERNELRELEASE
is correctly defined before dtbs_install happens.

+dtbs: scripts_dtc

dtbs: prepare3 scripts_dtc

+       $(Q)$(MAKE) $(build)=$(dtstree)
+
+dtbs_install: dtbs

Please do not have dtbs_install to depend on dtbs.

No install targets should ever trigger building anything
in the source tree.
