Wolfram Sang 24ce2d7b8b mmc: tmio: bring tuning HW to a sane state with MMC_POWER_OFF ... When powering off a card, we need to disable the tuning HW (like SCC for the Renesas SDHI) to get to a sane state and allow for re-tuning new cards. This was hidden before because we wrongly did that in hw_reset() before which was an unintended use of hw_reset(). Now that we corrected the use of hw_reset() meanwhile, we revealed this shortcoming and need to fix it properly by explicitly calling the downgrade callback.
