MLK-11071 cpufreq: imx7: add cpufreq pm_notifier on imx7d

Add pm_notifier for cpufreq on i.MX7D to make sure when
system do suspend/resume no cpu frequency change.
cpu frequency change may use the I2C/SPI interface to
control the external PMIC chip, if the I2C/SPI are not
active in this procedure, frequency change will fail.
