dts/Makefile: pass -undef -D__DTS__ to cpp
This brings U-Boot's cpp invocation into line with the way the Linux kernel invokes cpp on device trees. Consistency will be useful to ensure *.dts is portable between the two. -undef also has the added advantage of not defining "linux", so DT property names such as "linux,keymap" don't get mangled.
