[PATCH v3 5/5] ASoC: Use device_get_match_data()

[Rob Herring]

Use preferred device_get_match_data() instead of of_match_device() to
get the driver match data. With this, adjust the includes to explicitly
include the correct headers.

Signed-off-by: Rob Herring <robh@xxxxxxxxxx>
---
v3:
 - Move some header changes from patch 1 to here for rockchip_i2s_tdm.c,
   rockchip_pdm.c, smdk_wm8994.c, and tegra210_amx.c.
