With recent changes, trigger_pkg was split
into common definitions and type, and
component declarations.

8192 was giving us timing problems

In this way, we can save FPGA resources, as all acquisition
transactions from Post-Mortem are done via the external DDR.

Ever since we began using the infra_cores
submodule, the related SDB record is missing
from the top SDB layout.

Not sure why this happens, but this workaround
seems to work ok.

We must not count the special meta records in the
number of slaves. These will issue an error in recent
xwb_sdb_crossbar implementations.

As dsp-cores commit e2d16e4c36 changed mixer width,
we need to change it here. We need to be caution
here anyway, as a change in the mixer width will
not reflect to a change in the acquisition core
mixer width. Fix for this is pending.
