From: T Karthik Reddy <t.karthik.reddy at 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.
