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

The USB ports were still powered during S3, possibly leading to a
    higher power consumption. Note that, when the USB Always on
    feature is enabled, the USB ports are always powered, regardless
    of the USBP state.

The audio has been disabled as well, as it might consume some
    power or generate some noise.

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