Makefile: remove hardcoded device tree source directory

Browse Source 
Some boards that choose to utilize the OF_UPSTREAM directory for their
device tree files will need to specify that directory instead of the
traditional arch/$(ARCH)/dts/* path.

Include the correct path to the board's dtbs depending on if OF_UPSTREAM
is selected or not.
