add deviation for leaf constraint

[ram-mac]

power_admin_down_up_test is failing due to below error;
"Leaf 'name' inside the 'config' container must also be set to value '0/FC0' to satisfy the leafref constraint on the list key"

This error is for Leaf-ref validation for list keys which is enforced in XR, and this is fixed by setting the leaf in config container as well. While all other vendors work without this explicit configuration.

So there is deviation to track the behavior separately.
