ASoC: Do not write to invalid registers on the wm9712.
commit 48e3cbb3f67a27d9c2db075f3d0f700246c40caa upstream.
This patch fixes a bug where "virtual" registers were being written to the ac97
bus. This was causing unrelated registers to become corrupted (headphone 0x04,
touchscreen 0x78, etc).
This patch duplicates protection that was included in the wm9713 driver.
