From: T Karthik Reddy t.karthik.reddy@xilinx.com

Removed no-1-8-v property from zynqmp sdhci devicetree nodes to allow UHS-I capable SD cards to work in SD3.0 UHS modes.

Boards that does not have level shifter for SD, does not support 1.8v. so no-1-8-v property to sdhci dt nodes should be present in zcu102 Rev-A,B, zcu104 Rev-A,C, zcu100, zcu1275 Rev-B boards.
