This change adds the TLAST signal to the AXI streaming interface
of the source side for Intel targets.
Xilinx based designs already have this since the tlast is part of the
interface definition.
In order to make the signal optional and let the tool connect a
default value to the it, the USE_TLAST_SRC/DEST parameter is
added to the configuration UI. This conditions the tlast port on
the interface of the DMAC.
Xilinx handles the optional signals much better so the parameter
is not required there.
In DUAL mode half of the data ports are unused and the unused inputs need
to be connected to dummy signals.
Completely hide the unused ports in DUAL mode to remove that requirement.

Connect the DAC data underflow pin (fifo_rd_underflow) of the DMA
to the dunf pin of the device core. This way the software can detect
underflows in the DAC data path.
Explicitly disable the "Transfer Start Synchronisation Support"
since the sync lines are not connected in this project.
If the sync input line (s_axi_user[0] or fifo_wr_sync) are not connected,
Vivado 2017.4.1 no longer connects them to the defaultValue defined
in the axi_dmac ip (1). Instead he uses the defaulValue field defined
in the interface definition which in case of both interfaces is 0;
Rework the peripheral address to match the updated semantics of
ad_cpu_interconnect, which expects that the addresses are in the range of
0x00010000 - 0x001fffff. This includes updating the base addresses as well
as compressing the used address range to fit into the 2Mb window.

Currently the TX lane mapping is implemented by having to connect tx_phy_s_* to
the tx_ip_s_* and the tx_phy_d_* to the tx_ip_d_* signals in the system
qsys file in the desired order.
Re-work things so that instead the lane mapping is provided through the
TX_LANE_MAP parameter. The parameter specifies in which order logical lanes
are mapped onto the physical lanes.
The appropriate connections are than made inside the core according to this
parameter rather than having to manually connect the signals externally.
In order to generate a 1-to-1 mapping the TX_LANE_MAP parameter can be left
empty.
This change slightly reduces the boiler-plate code that is necessary to
setup the transceiver.

The PLL frequency must be half of the lane rate and the core clock rate
must be lane rate divided by 40. There is no other option, otherwise things
wont work.
Instead of having to manually specify PLL and core clock frequency derive
them in the transceiver script. This reduces the risk of accidental
misconfiguration.

Use the sys_dma_clk clock module for clock and reset signals of the data
path, rather than using the A10GX specific sys_ddr3_cntrl signals. This
enables compatibility for all Altera/Intel platforms.

Provide the correct lane mapping for the DAQ2 DAC lanes which do not follow
a 1-to-1 mapping between physical and logical lanes due to PCB layout
constraints.

Convert the DAQ2 project to the ADI JESD204 link layer cores. The change is
very straight forward, but a matching change on the software side is
required.

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:
