- The XADC was removed because the XADC IPI generates vaux inputs 0 and 10 even if 0 and 8 are selected

Reset generator's external reset signal was active low, but the GT reset is active high, and both the DDR controller and FIFO2S were in reset.
Therefore the external reset active state is changed to active high. This setup in general is made by the tool automatically, in order to do it correctly, need to
set this two property of the reset generator.

There can be a rather high latency between the last byte of a burst has been send and the time the response for the burst is received. Running at high samplerates this can cause the internal DMA store and forward FIFO to fill up and subsequently stall the DMA pipeline and drop samples. To better cope with the situation double the size of the internal FIFO. Also increase the clock of the AXI bus to be able to accommodate a samplerate of 310MHz.

The axi_dmac supports native AXI3, there is no need to add a interconnect
for protocol conversion between it and the HP port.
