Subject: [PATCH 1/2] ASoC: tegra30: ahub: Fix incorrect usage of of_device_get_match_data

const struct of_device_id incorrectly assigned "match->data" using
of_device_get_match_data()

Instead assign `const struct tegra30_ahub_soc_data *soc_data` with
const void *of_device_get_match_data(...)

Fixes: 80165bb80433 ("ASoC: tegra30: ahub: Use of_device_get_match_data")
