Can you list out which SoCs support it and which don't.  Having this list
will be useful in understanding which controller versions supported it.

P1020, p1021, p1022, p1024, p1015 and p4080 can't support it.
Mpc8536, p2020, and the other current DPAA silicon (e.g. p5020, p3041) support it.

Based on this, why don't we use the HOSTVER register to detect instead of device tree:

I've got a mild preference for handling quirk assignment in the DT
rather than in driver code, so I'd prefer to just push the original
patch to mmc-next as-is.  Does that sound okay?

(I think the argument that there isn't going to be any new hardware
with this problem is equally in favor of both methods.)

Thanks,

- Chris.
