Currently the makefile for arm64 builds all the DT files based on
rules in the arch/arm64/boot/dts/Makefile, as this is statically
passed via the $(build)= parameter. Change the $(build) parameter
to actually point to the subdir itself, so the makefile from
that subdir can be used to set-up build flags etc., for example
setting up DTC_FLAGS. The patsubst magic is used to strip the
trailing "/" from the path, as that confuses the kbuild system.
