gpio: Add devm_gpiod_unhinge()
This adds a function named devm_gpiod_unhinge() that removes the resource management from a GPIO descriptor. I am not sure if this is the best anglosaxon name for the function, no other managed resources have an equivalent currently, but I chose "unhinge" as the closest intuitive thing I could imagine that fits Rusty Russell's API design criterions "the obvious use is the correct one" and "the name tells you how to use it". The idea came out of a remark from Mark Brown that it should be possible to handle over management of a resource from devres to the regulator core, and indeed we can do that.
