[PATCH v4 5/5] mmc: dw_mmc: Remove DW_MCI_QUIRK_NO_WRITE_PROTECT

[Doug Anderson <dianders@chromium.org>]

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.

Signed-off-by: Doug Anderson <dianders@chromium.org>

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.
