Enable i.MX8MM cpu-idle using generic ARM cpu-idle driver, 2 states
are supported, details as below:

Changes since V5:
- improve state1 idle name to better match PSCI doc;
- remove wakeup-latency-us property as it is NOT necessary when entry-latency-us/exit-latency-us
exist.

Hi Anson,
I've applied the patches 1-3 but this one does not apply.
You can either respin it against tip/timers/core and take it through
Shawn's tree. If the later, you can add my Acked-by.

Hi, Shawn
Can you take this patch and add below Acked-by? It should can be applied to your tree directly.
Acked-by: Daniel Lezcano <daniel.lezcano@linaro.org>

Sorry that I just found this patch can NOT be applied to your for-next tree neither, so
I redo the patch against your for-next tree, so you can just skip this patch series now
(as Daniel already picked the rest 3 patches) and take that patch I just sent, link as below:
https://patchwork.kernel.org/patch/11097471/
Thanks,
Anson
