[218/264] ASoC: wm8711: Fix wrong mask for setting input audio data bit length select

[Greg KH]

3.1-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Axel Lin <axel.lin@xxxxxxxxx>

commit 04c57163c8edfbc50e022737014069998ba4fc5f upstream.

The Input Audio Data Bit Length Select is controlled by BIT[3:2] of
WM8711_IFACE(07h) register.
Current code incorrectly masks BIT[1:0] which is for Audio Data Format Select.
