CHROMIUM: tegra: asymptote: Suppress touch noise when on battery
Currently the atmel touch controller on asymptote will generate a lot of touch noise when the AC supply is removed and on battery. This patch tunes the parameter IDLEGCAFDEPTH and ACTVGCAFDEPTH of the touch controller object T28 to suppress these noise. BUG=None TEST=Manually tested on Asymptote and confirmed false detection is suppressed when AC supply is disconnected.
