My stance is that the driver is responsible of enabling and managing runtime PM for its hardware block(s). Runtime PM in the core should only be added if the core needs to be aware about it, such as is the case when e.g. a block device needs to drain its write buffer before going to runtime sleep. I fail so see why the GPIO core need to be aware about this.
In this very same thread at https://www.spinics.net/lists/arm-kernel/msg600515.html, you kind of proposed to handle this in the core in fact :-) Though indeed you said that the core could provide helpers.
