Properly teardown the sysctl node and detach child driver if gpiosim gets
...
detached itself (e.g. when the 'drvctl -d gpiosimX' command is entered).

For the sake of correctness, call pmf_device_deregister() in the detach

function.

With help from Matthias Drochner, thanks!

Simplify the use _a lot_ by hooking this to sysctl instead of bio(4).
...
When it attaches, it creates a hw.gpiosimN.value sysctl node which can
then be used to manipulate the simulated device state.

Rework the GPIO framework. Tie it to the kauth(9) framework to control
...
access to the GPIO pins. Device drivers using GPIO pins can now be
attached and detached at runtime. GPIO pins can be named for easier
reference from userland programs. Introduce a new gpiosim(4) driver,
which is used for development.
