The constraint where added to remove timing problems on the reset path.
The constraint paths do not match anymore. The resets are used in a synchronous
way so we don't need the timing exceptions anyway.

Xilinx recommends that all synchronizer flip-flops have
their ASYNC_REG property set to true in order to preserve the
synchronizer cells through any logic optimization during synthesis
and implementation.
