The polling rate is already specified in some devicetrees, like imx8mp.dtsi for example, but was not selected so far. For the trippoints, the cpu-thermal node is used. Also get the polling rate from this node. Use the default of 5000ms if the polling rate should not be specified in the devicetree.

NOTE: The polling rate from the devicetree will be used after this patch. In imx8*.dtsi devicetrees the polling delay is set to 2000ms for example.
