dt-bindings: input: iqs626a: Redefine trackpad property types 



Following a recent refactor of the driver to properly drop unused
device nodes, the driver expects trackpad channel touch thresholds
and ATI base values to be specified under single trackpad channel
child nodes.

This enhancement moves both properties to scalar values as opposed
to arrays, making their types consistent across bindings.
