Expose a touch_count sysfs attribute on both the Samsung (s6sy761) and FocalTech (edt-ft5x06) touchscreen drivers, incrementing on each finger release. This is needed by comma.sh to detect tap-based factory reset during early boot. Also fix comma.sh to reference input0 instead of input2 to match mainline kernel input device numbering. Tested on device: 1 tap=1, 3 taps=3, 5 taps=5.
Use /sys/class/input/input*/device/touch_count so comma.sh works on both mainline (input0) and vendor kernel (input2).
