dt-bindings: kbuild: Support partial matches with DT_SCHEMA_FILES

Browse Source 
DT_SCHEMA_FILES is currently restricted to a list of exact files with
the full source tree path (i.e. Documentation/devicetree/bindings/...).
Loosen this requirement and let DT_SCHEMA_FILES be a partial match.

With this, checking all schema files in a directory is possible:

$ make DT_SCHEMA_FILES=/gpio/ dt_binding_check

Or all schema files with 'qcom' in the path or filename:

$ make DT_SCHEMA_FILES=qcom dt_binding_check
