[PATCH] regulator: gpio-regulator: fix forgotten gpios-states reading

["Heiko Stübner" <heiko@sntech.de>]

From: Heiko Stuebner <heiko.stuebner@bqreaders.com>

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.
