Kaustabh Chakraborty 0932950d3a mmc: dw_mmc: add a quirk for accessing 64-bit FIFOs in two halves ...

[ Upstream commit 57c0902f8bec51add5a1eb908d8b876592725d81 ]

In certain DW MMC implementations (such as in some Exynos7870
controllers), 64-bit read/write is not allowed from a 64-bit FIFO.
Add a quirk which facilitates accessing the 64-bit FIFO registers in two
32-bit halves.
