[PATCH] kbuild: fix W= option checks for extra DTC warnings

[Masahiro Yamada]

> 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.
