Subject: [PATCH v3 1/2] dt-bindings: HID: i2c-hid: elan: Introduce Ilitek ili2901

The Ilitek ili2901 touch screen chip same as Elan eKTH6915 controller
has a reset gpio. The difference is that they have different
post_power_delay_ms and post_gpio_reset_on_delay_ms.
Ilitek ili2901 also uses 3.3V power supply.
