If HW supports SDHCI_TUNING_MODE_3 which is auto retuning, we won't retune during runtime suspend and resume, instead we use Re-tuning Request signaled via SDHCI_INT_RETUNE interrupt to do retuning and hw auto retuning during data transfer to guarantee the signal sample window correction. This can avoid a mass of repeatedly retuning during small file system data access and improve the performance.
