In some cases it makes sense to create a GPIO chip from the local driver
for a few GPIOs. Those should stay where they are.
At the same time it makes sense to get rid of code duplication in existing or
new coming drivers. For example, gpio-ml-ioh should be incorporated into
gpio-pch. In similar way gpio-intel-mid into gpio-pxa.
