MAINTAINERS: update arm,pl353-smc.yaml reference

The file name: Documentation/devicetree/bindings/mtd/arm,pl353-smc.yaml
should be, instead: Documentation/devicetree/bindings/memory-controllers/arm,pl353-smc.yaml.

Update its cross-reference accordingly.

Fixes: 813d527 ("MAINTAINERS: Add PL353 SMC entry")
Fixes: d3d0e1e ("dt-binding: memory: pl353-smc: Convert to yaml")
