Subject: [PATCH v3 1/1] checkpatch: Don't warn on "orhapned" DT schema file

Currently checkpatch warns is the DT schema file is absent in MAINTAINERS.
However the DT schema files are self-contained in this sense and
have embedded information about maintainers of it. This is a requirement.
Hence, avoid checkpatch warning about it.

v3: removed Requested-by tag
v2: drop some leftovers


The motivation of the patch is that DT people complaining about checkpatch but
doing nothing about it. They should be more collaborative.
