Im just looking at the system.dts here, it appears you have
"xlnx,has-cd = <0x0>;". Firstly do you not have the card detect signal
connected? if you don't have it connected "xlnx,has-cd" is not going
to do anything to help, you will need to use the boolean 'broken-cd'
or 'non-removable'. Have a look at the kernel mmc binding docs in
'Documentation/devicetree/bindings/mmc/mmc.txt'.

e.g.

&sdhci0 {
  status = "okay";
  broken-cd;
};
