ASoC: rt1308-sdw: fix random louder sound

This patch uses a vendor register to check whether the system hibernated ever.
The driver will only set the preset when the driver brings up or the system hibernated.
It will avoid the unknown issue that makes the speaker output louder and can't control the volume.
