mainboard/lenovo: Power off USB and mute audio before entering S3

Currently, the USB ports are still powered during S3, so turning
    them off may reduce the power consumption.
    Note that, when the USB Always on feature is enabled, the USB
    ports are always powered, regardless of the USBP state.

This patch also disables the audio, as it might consume some
    power or generate some noise.

Both the USB power and the audio are reenabled by coreboot during
    the poweron.
