MLK-11357-2 ARM: imx: add cpuidle support for imx7d
Enable cpuidle for i.MX7D, total 3 level idle supported:
1. ARM WFI;
2. WAIT mode;
3. Low power idle with ARM/SCU platform power off.
Only when system in low bus freq mode, system is able to
enter low power idle, and only when both of 2 cores are
in low power idle, ARM/SCU platform will be powered off.
DDR will be put into low power mode when low power idle
is entered.
