MAINTAINERS: adjust STARFIVE JH7100 PINCTRL DRIVER after file movement

Commit ba7fdf88e98a ("pinctrl: Create subdirectory for StarFive drivers")
moves pinctrl-starfive.c into its own subdirectory starfive; further,
commit ba99b756da17 ("pinctrl: starfive: Rename "pinctrl-starfive" to
"pinctrl-starfive-jh7100"") adds the suffix jh7100 to the driver and
dt-bindings header file name.

These commits however do not adjust the entry in MAINTAINERS. Hence,
./scripts/get_maintainer.pl --self-test=patterns complains about a broken
reference.

Adjust the entries for STARFIVE JH7100 PINCTRL DRIVER after file movement.
