Benson Leung b7090ee1d0 google/chell: Adjust nuvoton 8825 button thresholds, add properties
Set "nuvoton,sar-threshold" property to thresholds
based on tuning with the Android Wired Headphone
Compatibility Kit and Chell EVT.

Also set properties nuvoton,sar-compare-time and
nuvoton,sar-sampling-time.

The values of compare and sampling time align with
the ones from this CL:

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.
