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.

Tested on Toradex Colibri iMX7S

Hello, just a gently ping on this series. Thanks!
