[PATCH V2 02/15] mmc: core: Disable re-tuning when card is no longer initialized

Re-tuning is done before a request is sent to the card.
Host controller drivers can choose to enable re-tuning
when tuning is done during card initialization. To
ensure that re-tuning gets disabled, add disabling to
mmc_set_initial_state() which is called whenever the
card is powered on, off, or reset.
