mmc: core: Add SD card quirk for broken discard
Some SD-cards from Sandisk that are SDA-6.0 compliant reports they supports
discard, while they actually don't. This might cause mk2fs to fail while
trying to format the card and revert it to a read-only mode.
To fix this problem, let's add a card quirk (MMC_QUIRK_BROKEN_SD_DISCARD)
to indicate that we shall fall-back to use the legacy erase command
instead.
