google/chell: Adjust nuvoton 8825 button thresholds again.

Changing these thresholds again for new tuning in March of 2016.
    Something's changed in the latest firmware to cause all
    values previously read on Chell to float down.

Set "nuvoton,sar-threshold" property to thresholds
    based on tuning with the Android Wired Headphone
    Compatibility Kit and Chell DVT.

BUG=chrome-os-partner:49333
    BRANCH=none
    TEST=Run evtest, selecting the input event for sklnau8825adi
    Using the Nominal headphones from the kit, check that the
    buttons for "KEY_VOLUMEDOWN", "KEY_VOLUMEUP", "KEY_MEDIA",
    and code 582 (?) (should be voice search, but evtest doesn't understand)
    All of these buttons should work properly.
