DTC 1.4.2 or later checks DT unit-address without reg property and vice-versa, and generates lots of warnings. Fixing DT files will take for a while. Until then, let's turn off the check unless building with W=*.
Introduce a new helper dtc-option to check if the option is supported in order to suppress warnings on older versions.

This is one possible answer to Tom's: https://www.mail-archive.com/u-boot@lists.denx.de/msg240328.html
He fixed the problem on travis-ci by commit a0f3e3d, but it is still annoying during the regular development. Perhaps we may want to hide the warnings (at least hidden in Linux Kernel by default). Or, is it better to keep it noisy to motivate people to fix their DT files? I am not quite sure...
Now I am sending this as RFC patch in case people may want to start discussion.
BTW, this is a counter-part of the patch I sent to the Kbuild sub-system (https://patchwork.kernel.org/patch/9592747/) because I want the U-Boot build system with Linux as much as possible. Let's see if I will get possible opinions in the Kbuild review.

Seems like a good idea to me, at least until more are converted.
