ARM: tegra: stingray: noise suppression tuning in touch file

Noise Threshold value updated to reduce occurance
rate of frequency hopping.
This helps with idle mode current drain and reduces
occurance of cycle overruns.
Active to idle scan mode time out is changed to
2 seconds as opposed to 5 seconds to lower current
drain.
