dt-bindings: input: HID: i2c-hid: Introduce bindings for the Goodix GT7375P

This adds new bindings for the Goodix GT7375P touchscreen.  While this
touchscreen's communications are based on the generic "i2c-over-hid"
protocol, it needs special power sequencing and thus gets its own
compatible and bindings.
