To be able to read the T junction on i.MX CPU the imx-cpufreq-dt needs to be loaded, however this is currently not the case for i.MX7S given that it does have only one operating frequency. Add "fsl,imx7s" to cpufreq-dt-platdev blocklist and a single frequency operating point to the CPU. With that it is now possible to correctly read the CPU T junction.
