Istvan Csomortani 81fa65cd51 avl_dacfifo: Few cosmetic changes on avl_dacfifo_wr
+ avl_write_transfer_done_s is a redundant net
 + specify the net state explicitly on if statements
 + to define the edge of avl_mem_fetch_wr_address signal,
its register and its second sync register should be used

Istvan Csomortani a1539a62b7 avl_dacfifo: Integrate util_delay into dac_xfer_out path
The ad_mem_asym memory read interface has a 3 clock cycle delay, from the
moment of the address change until a valid data arrives on the bus;
because the dac_xfer_out is going to validate the outgoing samples (in conjunction
with the DAC VALID, which is free a running signal), this module will compensate
this delay, to prevent duplicated samples in the beginning of the
transaction.

Istvan Csomortani 04f397f688 avl_dacfifo: Fix a few control signals
+ avl_last_transfer depends on the avl_xfer_req state
  + avl_xfer_req will be asserted after the last avalon write
transfer

Istvan Csomortani 8f9cadb017 avl_dacfifo: Fix the avl_write generation
The asymetric memory has a 3 clock cycle delay on its read
interface, therefor the minimum distance between two consecutive
avalon write should be 3.

Istvan Csomortani f456ebc6f0 avl_dacfifo: Few cosmetic changes on avl_dacfifo_wr
+ all net names should have a *_s postfix
  + avl_burstcount is a constant 1, no need for an additional
register for it
  + all CDC should have two synchronization register, add
avl_last_beat_req_m2

Istvan Csomortani 9055774795 all: Update license for all hdl source files
All the hdl (verilog and vhdl) source files were updated. If a file did not
have any license, it was added into it. Files, which were generated by
a tool (like Matlab) or were took over from other source (like opencores.org),
were unchanged.

New license looks as follows:
