The original quirk was added in the change 'mmc: dw_mmc: add quirk to
indicate missing write protect line'. The original quirk was added at
a controller level even though each slot has its own write protect (so
the quirk should be at the slot level). A recent change (mmc: dw_mmc:
Add "disable-wp" device tree property) added a slot-level quirk and
support for the quirk directly to dw_mmc.

Changes in v4:
- New for this version; addresses comments from Olof Johansson about
the fact that we shouldn't have both a slot and controller level
quirk for the same thing.
