When building specific DTBs out of the kernel tree the vendor subdirs
(boot/dts/<vendor>) are not created, ensure that they are before
building the DTB.

Problem is visible with arm64 for out of tree builds.
make O=/tmp/kkk/ defconfig
make O=/tmp/kkk/ cavium/thunder-88xx.dtb
DTC arch/arm64/boot/dts/cavium/thunder-88xx.dtb
cc1: fatal error: opening output file
arch/arm64/boot/dts/cavium/.thunder-88xx.dtb.dts.tmp: No such file or
directory
compilation terminated.
make[2]: *** [arch/arm64/boot/dts/cavium/thunder-88xx.dtb] Error 1
make[1]: *** [cavium/thunder-88xx.dtb] Error 2
Building specific dtb target on arm32 is working fine
make O=/tmp/kkk4/ multi_v7_defconfig
make O=/tmp/kkk4/ zynq-zc702.dtb
This is the way how Yocto is building dtb for specific target.
