[PATCH] gpio: shared: drop the parent check for reset-gpio devices

[Tyler Baker <tyler.baker@oss.qualcomm.com>]

gpio_shared_dev_is_reset_gpio() requires the reset-gpio device's parent
to carry the GPIO chip's fwnode. Once the reset core parents that device
to the GPIO controller instead, this fails on controllers with a
gpio_chip and fwnode per bank, so their shared reset lines are no longer
matched.

The check is redundant: only devices compatible with "reset-gpio" get
here, and their reset-gpios reference must already name the chip's
fwnode. Drop it.
