dt-bindings: touchscreen: fsl,imx6ul-tsc: support glitch thresold
Support the debounce-delay-us property.
Drivers must convert this value to IPG clock cycles and map it to one of
the four discrete thresholds exposed by the TSC_DEBUG_MODE2 register:
0: 8191 IPG cycles
1: 4095 IPG cycles
2: 2047 IPG cycles
3: 1023 IPG cycles
