mmc: quirks: add support for quirks based on EXT_CSD_REV
This change allows the usage of quirks based on
the register value of EXT_CSD_REV. It was seen for several
eMMC cards that same issues, such as data corruption
while using cache, were relevant for all eMMC cards
having the same EXT_CSD_REV value.
This change allows us to distinguish between cards based
on this register.
