mfd: stmpe: Probe sub-function by compatible
Use sub-function of_compatible during probe, instead of using the node
name. The code should not rely on the node names during probe, in
addition to that the previously hard-coded node names are not compliant
to the latest naming convention (they are not generic and they use
underscores), and it was broken by mistake already once [1].
