mb/lenovo/x1_carbon_gen1/acpi: call MUTE(1) and USBP(0) on _PTS
Like with any other Thinkpad, call MUTE(1) and USBP(0) on _PTS on the
Lenovo Thinkpad X1 Carbon 1st generation.
Without MUTE(1) the speakers sometimes glitch before going into S3 (if not
muted), while without USBP(0) the USB ports are always powered in S3,
regardless of the USB Always-On mode selected.
