mmc: dw_mmc: fix suspend/resume operation
This patch is related to re-init processing on suspend/resume. When card is resuming, some register is reset. If card is removable, maybe controller should be rescan for card. But if assume card is non-removable, need to restore the old value at registers. We store the value of FIFOTH at probe time and then restore it in dw_mci_resume().
