[PATCH v1 12/16] gpio: stmpe: Utilize helpers from string_choices.h

From: Andy Shevchenko
Date: Mon Mar 06 2023 - 14:56:00 EST


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.
