3.5.7.28 -stable review patch. If anyone has any objections, please let me know.
------------------
From: Bo Shen <voice.shen at atmel.com>
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.
