[PATCH] ASoC: imx-audmux: Add driver suspend and resume to support MEGA Fast

For i.MX6 SoloX, there is a mode of the SoC to shutdown all power source of modules during system suspend and resume procedure. Thus, AUDMUX needs to save all the values of registers before the system suspend and restore them after the system resume. Signed-off-by: Shengjiu Wang ---
