[PATCH] dt-bindings: don't anchor DT_SCHEMA_FILES to bindings directory

["André Draszik" <git@andred.net>]

From: André Draszik <andre.draszik@linaro.org>

Commit 5e3ef4546819 ("dt-bindings: ignore paths outside kernel for
DT_SCHEMA_FILES") anchored all searches to the bindings directory
(since bindings only exist below that), but it turns out this is not
always desired.

Just anchor to the base kernel source directory and while at it, break
the overly long line for legibility.
