Subject: [PATCH] kbuild: compute the dtbs_install destination more simply
The 'dtbinst_root' is used to remember the root of the in-kernel dts
directory (i.e. arch/*/boot/dts), but it looks clumsy.
I prefer using two variables 'obj' and 'dst' to track the in-kernel
directory and the install destination, respectively.
