lenovo/x60: add hda_verb.c

This creates a config for the x60 audio based
    on values taken from vendor bios.

The pin config is stored in (for linux 4.5 at least):
    /sys/class/sound/card0/hw*/init_pin_configs
    In the left column there is the pin number.
    In the right column there is the default configuration of that pin.
    (This has to be done while running the proprietary bios)

More information on the sound card can be found in:
    /proc/asound/card0/codec#*
    This also hold the information of /sys/class/sound/

What is improved:
    - internal microphone is chosen by default
    - when jack is inserted it is chosen instead of internal speaker

Before this had to be done manually in alsa or pulseaudio.

TEST= check if internal microphone is used by default in
    pavucontrol if you are using pulseaudio.
    Plug in a jack with headphones and check if there
    is sound output through these and not the build-in
    speaker.
