cpufreq: Add imx-cpufreq-dt driver
Right now in upstream imx8m cpufreq support just lists a common subset of OPPs because the higher ones should only be attempted after checking speed grading in fuses. Add a small driver which checks speed grading from nvmem cells before registering cpufreq-dt. This driver allows unlocking all frequencies for imx8mm and imx8mq and could be applied to other chips like imx7d Signed-off-by: Leonard Crestez <leonard.crestez@nxp.com> Signed-off-by: Viresh Kumar <viresh.kumar@linaro.org>
