kbuild: Report enabled nodes with duplicated address
Duplicated unit address is a normal case, as long as no more than one
node using that address is enabled. Having duplicated addresses is
already allowed by '-Wno-unique_unit_address' in DTC_FLAGS. But two
simultaneously enabled nodes sharing the same address is usually
incorrect. Add '-Wunique_unit_address_if_enabled' flag to report
warnings for such case when doing "make dtbs_check".
