Series input: iqs269a: Add support for slider gestures and OTP variants | expand

Commit Message

This patch adds bindings for the D0 order code of the device. This
order code represents an OTP variant that enables a touch-and-hold
function in place of slider 1.

Also included is the ability to specify the 00 order code (default
option with no OTP customization) explicitly.
