2019-02-25mmc: sdhci-esdhc-imx: fix HS400 timing issueBOUGH CHEN
Now tuning reset will be done when the timing is MMC_TIMING_LEGACY/ MMC_TIMING_MMC_HS/MMC_TIMING_SD_HS. But for timing MMC_TIMING_MMC_HS, we can not do tuning reset, otherwise HS400 timing is not right. Here is the process of init HS400, first finish tuning in HS200 mode, then switch to HS mode and 8 bit DDR mode, finally switch to HS400 mode. If we do tuning reset in HS mode, this will cause HS400 mode lost the tuning setting, which will cause CRC error.

Therefore periodical work is scheduled but the rehash never happens. So allow to enable/disable rehash for the whole group, which is added per-profile. Disable rehashing for MR profile. Addition to the vregion list is done only in case the rehash is enable on the particular vregion. Also, the addition is moved after delayed work init to avoid schedule of uninitialized work from vregion_rehash_intrvl_set(). Symmetrically, deletion from the list is done before canceling the delayed work so it is not scheduled by vregion_rehash_intrvl_set() again.
