Subject: ASoC: wm8731: fix dsp mode configuration
From: Bo Shen <voice.shen@xxxxxxxxx>
commit b4af6ef99a60c5b56df137d7accd81ba1ee1254e upstream.
According to WM8731 "PD, Rev 4.9 October 2012" datasheet, when it
works in DSP mode A, LRP = 1, while works in DSP mode B, LRP = 0.
So, fix LRP for DSP mode as the datesheet specification.
