[PATCH] ALSA: hda/cirrus_scodec_test: Fix incorrect setup of gpiochip

[Richard Fitzgerald <rf@opensource.cirrus.com>]

Set gpiochip parent to the struct device of the dummy GPIO driver
so that the software node will be associated with the GPIO chip.

The recent commit e5d527be7e698 ("gpio: swnode: don't use the
swnode's name as the key for GPIO lookup") broke cirrus_scodec_test,
because the software node no longer gets associated with the GPIO
driver by name.

Instead, setting struct gpio_chip.parent to the owning struct device
will find the node using a normal fwnode lookup.
