Subject: [PATCH] arm64: dts: qcom: sc8280xp-x13s: fix touchscreen power on

The Elan eKTH5015M touch controller on the X13s requires a 300 ms delay before sending commands after having deasserted reset during power on.

Switch to the Elan specific binding so that the OS can determine the required power-on sequence and make sure that the controller is always detected during boot.

Note that the always-on 1.8 V supply (s10b) is not used by the controller directly and should not be described.
