Subject: [PATCH v1 06/16] gpio: adnp: Utilize helpers from string_choices.h

There are a few helpers available to convert a boolean variable
to the dedicated string literals depending on the application.
Use them in the driver.

While at, utilize specifier field for padding the strings where
it's required.
