    dtc: Improve and better integrate dtc and libfdt Makefiles
    
    This patch substantially revamps the dtc Makefiles, in particular
    better integrating the Makefile for dtc proper with the Makefiles
    imported from libfdt for libfdt and the shared testsuite.  Notable
    changes:
    	- No recursive make calls.  Instead subsidiary Makefiles are
    included into the top-level Makefile so we get a complete dependency
    information.
    	- Common pattern rules, CFLAGS etc. shared between dtc, libfdt
    and testsuite, rather than separate copies.
    	- Vaguely Kbuild-like non-verbose mode used by default, which
    makes warnings more prominent.
    	- libfdt Makefile consists only of variable definitions and
    helper rules, to make it more easily embeddable into other Makefile
    systems.
