regulator: gpio-regulator: fix forgotten gpios-states reading
Commit 934624d6e9f0 ("regulator: gpio-regulator: do not open-code counting
and access of dt array elements") forgot to convert the recently added
gpios-states property using the same pattern.
Convert this instance to use the of-helpers too, resolving the build error.
