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().
