MAINTAINERS: rectify entry for ALLWINNER HARDWARE SPINLOCK SUPPORT

Commit f9e784dc ("dt-bindings: hwlock: add sun6i_hwspinlock") adds
Documentation/devicetree/bindings/hwlock/allwinner,sun6i-a31-hwspinlock.yaml,
but the related commit 3c881e05 ("hwspinlock: add sun6i hardware
spinlock support") adds a file reference to
allwinner,sun6i-hwspinlock.yaml instead.

Hence, ./scripts/get_maintainer.pl --self-test=patterns complains:

  warning: no file matches  F:  Documentation/devicetree/bindings/hwlock/allwinner,sun6i-hwspinlock.yaml

Rectify this file reference in ALLWINNER HARDWARE SPINLOCK SUPPORT.
