We must specify the value of audmux pinctrl if we want to use pinctrl_pm(). Thus change bypass value 0x80000000 to what we exactly need.
This patch also seperately unset PUE bit for TXD so that IOMUX won't pull up/down the pin after turning into tristate. When we use SSI normal mode to playback monaural audio via I2S signal, there'd be a pulled curve occur to its signal at the second slot if setting PUE bit for TXD. And it will make the second channel to play a constant noise. So by keeping the signal level in the second slot, we can get a constant high level signal (-1) or a low level one (0).

We have moved all pin groups settings into arch/arm/boot/dts/imx6qdl-pingrp.h. I just rebased and applied the patch. Please check my imx/dt branch and ensure I applied the changes correctly.
Simply perfect. Thank you. Nicolin
