ARM: imx: add i.MX7ULP cpuidle support
This patch adds cpuidle support for i.MX7ULP, 3 cpuidle
states supported as below:
1. WFI, just ARM wfi;
2. WAIT mode, mapped to SoC's partial stop mode #3;
3. STOP mode, mapped to SoC's partial stop mode #1.
In WAIT mode, system clock and bus clock will be enabled;
In STOP mode, system clock and bus clock will be disabled.
