MAINTAINERS: repair file entry in ADP1050 HARDWARE MONITOR DRIVER

Commit 4e1008d8aae5 ("dt-bindings: hwmon: pmbus: adp1050: add bindings")
adds the ADP1050 HARDWARE MONITOR DRIVER section, but slips in a typo in
its file entry.

Fortunately, ./scripts/get_maintainer.pl --self-test=patterns complains
about this broken reference.

Fix the typo in ADP1050 HARDWARE MONITOR DRIVER maintainer entry.
