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.
