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.
