axi_ad9361: Add CDC constraints Add proper constraints for all the CDC synchronizer paths to the axi_ad9361 core. Signed-off-by: Lars-Peter Clausen <lars@metafoo.de>

axi_ad9361: Preserve 1bit CDCs with ASYNC_REG true

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.
