[meta-xilinx] MMC timeout with linux-yocto-48

[Philip Balister]

I'm seeing this on a custom zynq board with Linux-yocto-4.8. Nathan
Rossi confirmed he could dupe this on a zybo. Booting mainline with the
multi_v7... config works though. Furthering moving around suggests
linux-yocto-48 will work, if we can figure out the magic kernel config
option.

Anyone see this? Any suggestions where to look? Nothing obvious jumps
out by inspection.
