Drive all output pins of the disabled interfaces with a constant value.
This avoids warnings from the tools about not driven output ports.

Mark all unused output ports explicitly as explicitly. This makes it clear
that they are left unconnected on purpose and avoids warnings from the
tools about unconnected ports.

Group the axi_dmac parameters by function and provide a human readable name
for the IPI GUI. This makes it easier to understand what parameter does
what when using the IPI GUI to configure the core.

Add validation values for the different configuration parameters. This
enables the tools to check whether the configured value is valid and avoids
accidental misconfiguration.

The address width for the AXI-Lite configuration bus for the core is only
14 bit. Remove the upper unused bits from the public interface.
This allows infrastructure code to know about this and it might be able to
perform optimizations of the interconnect based on this.

Move the clock and reset signals of the m_axi_src interface next to the
other signals in the module definition.

According to the documentation when using a BRAM block in SDP mode the
REGCEB pin is not used and should be connected to GND. The tools though
when inferring a BRAM connect REGCEB to the same signal REGCEA. This causes
issues with timing verification since the REGCEB pin is associated with the
write clock whereas the REGCEA pin is associated with the read clock.
Until this is fixed in the tools mark all paths to the REGCEB pin as false
paths.

The axi_dmac core is now capable of detecting whether its different parts
run in different clock domains or not. No need to configure it manually any
more.
