dt-bindings: input: touchscreen: ilitek_ts_i2c: Absorb ili2xxx bindings
While Linux uses a different driver, the Ilitek
ILI210x/ILI2117/ILI2120/ILI251x touchscreen controller Device Tree
binding documentation is very similar.
- Drop the fixed reg value, as some controllers use a different
address,
- Make reset-gpios optional, as it is not always wired.
