ASoC: simple-card-utils: Add simple_util_remove_jack()

simple_util_init_jack() acquires a GPIO descriptor with
gpiod_get_optional() and hands it to snd_soc_jack_add_gpios(), which
additionally installs an IRQ handler, a PM notifier, a delayed work and
a sysfs export for it. simple-card-utils has no counterpart that
releases any of this again.

Add simple_util_remove_jack(), the counterpart of
simple_util_init_jack(). It releases the jack GPIO and everything
snd_soc_jack_add_gpios() installed for it via snd_soc_jack_free_gpios(),
and clears sjack->gpio.desc so the descriptor is not left dangling after
it has been put.

This gives the generic card drivers a card->remove() path to release the
jack when the card goes away. The devres cleanup alone is not enough:
it is tied to the platform device, so it does not run when the card is
unregistered and re-registered while the platform device stays bound -
for example when a codec component is unbound and bound again.
