Merge tag 'imx-soc-5.3' of git://git.kernel.org/pub/scm/linux/kernel/git/shawnguo...

i.MX SoC changes for 5.3:
 - Switch imx7d to imx-cpufreq-dt for speed-grading, as imx-cpufreq-dt
   driver can handle speed grading bits on imx7d just like on imx8mq.
 - Improve imx6 cpuidle driver to use raw_spinlock_t.  The change makes
   no difference for !RT build, but is required by RT kernel.
