MAINTAINERS: Repair file entry in MARVELL 88PM886 PMIC DRIVER

Commit f53d3ef ("MAINTAINERS: Add myself for Marvell 88PM886 PMIC")
adds a file entry referring to drivers/regulators/88pm886-regulator.c,
but the directory is actually called drivers/regulator. Note that there is
no 's' at the end.

Hence, ./scripts/get_maintainer.pl --self-test=patterns complains about a
broken reference.

Repair the file entry in the MARVELL 88PM886 PMIC DRIVER section.
