[V3,0/2] mmc: sdhci-sprd: Add SD HS mode online tuning

Message

Change in v3:
- Move changes in include/linux/mmc/host.h and drivers/mmc/core/sd_ops.c into patch1
- The callback is executed when timing is equal to MMC_TIMING_SD_HS
- Rename prepare_hs_tuning to prepare_sd_hs_tuning
- Rename execute_hs_tuning to execute_sd_hs_tuning

Change in v2:
- add mmc_sd_switch() and mmc_send_status() to the header file
- split up core changes from host driver changes
- Use pr_debug instead of dev_info and dev_dbg
- Optimize the best sampled value algorithm
