ARM: dts: imx7s: define speed_grade for cpufreq OPP table
imx-cpufreq-dt driver needs speed_grade to be defined
for correct probe and registration. The speed grade
is defined by two speed grading bits present in OCOTP fuses.
It fixes the following error:
root@colibri-imx7-02951832:~# dmesg | grep cpufreq
[ 2.222317] imx-cpufreq-dt: probe of imx-cpufreq-dt failed with error -2
For all imx7s parts speed grade is fixed at 800mhz.
