Normally writes to SDIO function 0 outside the vendor specific CCCR
registers are prohibited.
To support embedded devices that require writes to SDIO function 0 outside
this range (e.g. TI WL127x embedded sdio wifi device),
MMC_QUIRK_LENIENT_FN0 is introduced.
A card quirks field is added to `struct mmc_card' to support non-standard
devices (e.g. embedded sdio devices).
