mmc: Add MMC_QUIRK_BROKEN_SD_CACHE for Kingston Canvas Go Plus from 11/2019
[ Upstream commit c467c8f081859d4f4ca4eee4fba54bb5d85d6c97 ]
This microSD card never clears Flush Cache bit after cache flush has
been started in sd_flush_cache(). This leads e.g. to failure to mount
file system. Add a quirk which disables the SD cache for this specific
card from specific manufacturing date of 11/2019, since on newer dated
cards from 05/2023 the cache flush works correctly.
Fixes: 08ebf903af57 ("mmc: core: Fixup support for writeback-cache for eMMC and SD")
