Currently the makefile is setup in such manner that even if we build a DT file in a subdirectory under arch/arm/boot/dts, it gets built based on the base boot/dts/Makefile rules. This patch modifies the base makefile in such manner, that it detects which makefile to use based on build target path. This allows setting for example per-directory DTC_FLAGS and using those for the subdir build. The dtbdir local variable is setup to target to the build path.
