cpufreq: Add i.MX7S to cpufreq-dt-platdev blocklist

The i.MX 7Solo currently does not have multiple operating points,
however, in order for the i.MX Thermal driver to successfully probe
a cpufreq device is required. Add it to the cpufreq-dt-platdev
driver's blocklist to allow using imx-cpufreq-dt.
