For VER_0 tsens shares the device with the clock controller, but nevertheless it does not use syscon for these registers. Drop syscon_node_to_regmap() and acquire the regmap on our own. apq8064 has tsens as a part of gcc device tree node, ipq8064 puts tsens node as a child node of gcc. Thus check whether tsens resource can be fetched either from the device itself or from it's parent.
