ASoC: Tegra: Don't store snd_soc_jack_gpio in an array

Storing the struct in an array makes the assignments to the GPIO member a
little non-obvious, and is pointless when there's only a single GPIO.

(I thought I fixed this during the review cycle when first submitting this
driver, but I guess I overlooked that)
