powerpc/boot: Fix build of dts/fsl
The lkp robot reported that some configs fail to build, for example
mpc85xx_smp_defconfig, with:
cc1: fatal error: opening output file arch/powerpc/boot/dts/fsl/.mpc8540ads.dtb.dts.tmp: No such file or directory
This bisects to:
cc8a51ca6f05 ("kbuild: always create directories of targets")
Although that commit claims to be about in-tree builds, it somehow
breaks out-of-tree builds. But presumably it's just exposing a latent
bug in our Makefiles.
We can fix it by adding to targets for dts/fsl in the same way that we
do for dts.
