arm64: dts: qcom: sc8280xp-x13s: enable alternate touchpad
Enable both touchpad nodes in the devictree and let the HID driver determine which one is actually populated (by attempting to read from each i2c address). Ideally this would not be needed and the boot firmware should instead enable only the node for the populated touchpad, but this is unlikely to ever be realised for the X13s. Note that the pin configuration must currently be moved to the parent i2c-bus node even though only one of these nodes will ever be successfully probed on a specific device (e.g. to allow them to be probed in parallel).
