kbuild: fix W= option checks for extra DTC warnings
Kbuild supports 3 levels of extra warnings, and multiple levels can
be combined, like W=12, W=123. It was added by commit a6de553da01c
("kbuild: Allow to combine multiple W= levels").
From the log of commit 8654cb8d0371 ("dtc: update warning settings
for new bus and node/property name checks"), I assume:
- unit_address_vs_reg, simple_bus_reg, etc. belong to level 1
- node_name_chars_strict, property_name_chars_strict belong to level 2
However, the level 1 warnings are displayed by any argument to W=.
On the other hand, the level 2 warnings are displayed by W=2, but
not by W=12, or W=123.
Use $(findstring ...) like scripts/Makefile.extrawarn.
