Laszlo Nagy ae02773480 axi_dacfifo: Rewrote constraints to be more specific
Some of the wildcards matched too many paths and disabled the timing
checks on intraclock paths.

Istvan Csomortani 85a7cebc0e axi_dacfifo: Major update and redesign
Redesign the axi_dacfifo, to increase the supported datarates.
Major modifications:
  + The FIFO consist of two module: WRITE and READ. The axi_dacfifo_dac
was deprecated.
  + Both the AXI write and AXI read transaction are controlled by two
FSM, to increase redability of the code.
  + Support all the possible burst lengths [0..225], handles the last
fractional burst on both sides correctly.
  + Common reset architecture throughout the design, all the internal
registers and memories are reset on the posedge of dma_xfer_req
  + Delete all Altera related sources, for Altera projects
avl_dacfifo should be used.

Istvan Csomortani ac2e5a9dac constraints: Update constraints
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.
