common: Disable TTC0 MMIO routing for PS7

We do not use the ttc0 to MMIO routing, but it is enabled by default, so
explicitly disable it.

util_dac_unpack: Drive unused ports to 0

util_dac_unpack: Don't use localparam symbols in input/output signals

When using a localparam for the width of a input/output signal the tools
won't be able to infer the size of the signal. This results in the signal
always being only 1 bit wide which causes the design to not work.

util_adc_pack: Hide unused signals

Hide unused signals based on the number of selected channels. This silences
a few warnings from the tools about unconnected pins.

axi_dmac: Fix dummy AXI a{r,w}len fields width

The dummy a{r,w}len fields should have the same width as the real a{w,r}len
fields in order to not break auto AXI bus version detection.

fmcomms2: Set dac_unpack channels to 4

There are only 4 DAC channels in the fmcomms2 design, so set the number of
channels of the dac_unpack core to 4. This slightly reduces resource usage
as well as reducing the DMA alignment requirement from 128bit to 64bit.  The
later value is what existing applications expect the alignement requirement
to be.

fmcomms2: Connect DMA directly to the HP ports

The DMA controller is able to send AXI3 compatible requests, no need to add
a interconnect for protocol conversion in between the DMA controller and the
HP port.

axi_dmac: Add clock signal spec for m_axis/s_axis bus

This silences warnings from the tools about having no clock assigned to the bus.
Also fix the name of the TVALID signal.

The fifo_wr_sync signal is only used when C_SYNC_TRANSFER_START = 1, so hide it otherwise.
