tuna: update touch ic firmware to 0x61/0x41
- changed signal frequency to suit 60fps LCD
- have implemented features which fixed issues related to queue.
- Changing frequency is made to gain more margin at noisy environment.
Since LCD at 60fps has harmonics noise of 77.7kHz. It is safer to use lower signal
frequency to avoid the noise. i.e if we use 416kHz, 5% of variation to either
direction cause 41.6kHz shift, while 34.5kHz is shifted at signal frequency 345kHz.
