mmc: core: Add quirk for incorrect manufacturing date

Some eMMC vendors need to report manufacturing dates beyond 2025 but are
reluctant to update the EXT_CSD revision from 8 to 9. Changing the
Updating the EXT_CSD revision may involve additional testing or
qualification steps with customers. To ease this transition and avoid a
full re-qualification process, a workaround is needed. This
patch introduces a temporary quirk that re-purposes the year codes
corresponding to 2010, 2011, and 2012 to represent the years 2026, 2027,
and 2028, respectively. This solution is only valid for this three-year
period.

After 2028, vendors must update their firmware to set EXT_CSD_REV=9 to
continue reporting the correct manufacturing date in compliance with the
JEDEC standard.

The `MMC_QUIRK_BROKEN_MDT` is introduced and enabled for all Sandisk
devices to handle this behavior.
