Add cpuidle support for i.MX6SL, currently only support two cpuidle levels(ARM wfi and WAIT mode), and add software workaround for WAIT mode errata as below:
ERR005311 CCM: After exit from WAIT mode, unwanted interrupt(s) taken during WAIT mode entry process could cause cache memory corruption.
Software workaround: To prevent this issue from occurring, software should ensure that the ARM to IPG clock ratio is less than 12:5 (that is < 2.4x), before entering WAIT mode.
