Lars-Peter Clausen 988bf60747 axi_ad9361: Add ASYNC_REG properties to CDC regs and add missing -datapath_only 
Set the ASYNC_REG property on the bit synchronizer CDC control regs. This
hint to Vivado that the registers are used for CDC purposes.

Also use -datapath_only for the set_max_delay constraints on the CDC data
path to remove the hold time requirement.
