[PATCH v1 1/2] ARM: dts: imx7s: Define operating points table for cpufreq

[Francesco Dolcini <francesco.dolcini@toradex.com>]

From: Denys Drozdov <denys.drozdov@toradex.com>

Processor operating points for imx7s.dtsi should be properly defined to
perform correct imx-cpufreq-dt probe and registration and provide an
access to the temperature sensors using the i.MX thermal driver.
