MLK-18426 AMR64: dts: imx: Increase the cpuidle latency setting on imx8mm
After the WAIT mode is enabled on imx8mm, the previous latency setting
seems can NOT meet the system the latency requirement. audio playback is
impacted by cpuidle. So increasing the latency setting as large as possible
to eliminate the impact of system performance. The latency value is not very
accurate, need to be updated after we have enough performance test result.
