kbuild: turn of dtc unit address warnings by default
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.
