ASoC: rockchip: add workaround for silence of rk3288 ACODEC 
This patch adds reset and precharge in shutdown of PCM device.

ACODEC goes to silence if we change Fs to 44.1kHz from 48kHz. This
workaround seems to work but I don't know this workaround is correct
sequence or not for ACODEC.

ASoC: rockchip: support ACODEC for rk3328 
This patch adds support for audio CODEC core of rk3328.

Rockchip does not publish detail specification of this core
but driver source code is opened on their GitHub repository.
  https://github.com/rockchip-linux/kernel

So I ported this code to linux-next and added some trivial fixes.
