MAINTAINERS: adjust file entry in INTEL STRATIX10 FIRMWARE DRIVERS

Commit fbfb649 ("dt-bindings: firmware: stratix10: Convert to
json-schema") renames intel,stratix10-svc.txt to intel,stratix10-svc.yaml
in Documentation/devicetree/bindings/firmware/ as part of this dt-binding
conversion, but misses to adjust the file entry in INTEL STRATIX10 FIRMWARE
DRIVERS.

Adjust the file entry after the conversion.
