dt-bindings:nvpps:Add ts-capture-interval property

Browse Source 
Add documentation for 'ts-capture-interval' property.
This property allows configuring the interval between timestamp
captures in milliseconds (valid range: 100ms-1000ms), determining how
frequently the driver collects timestamp data.
If unspecified, timestamps are collected every 1000ms (1s) by default.
