The register read logic is not that complicated that it needs two extra
pipeline stages. It can easily be condensed into a single combinatorial and
still meet timing with large margins.

Disable registers in the register map which are not needed for this core.
This reduces the utilization of the core.

Declaring local parameters in the module parameter list is not valid
verilog. For some reasons Vivado accepts it nevertheless so the code has
worked so far. But this is not true for other tools, so move the local
parameter definitions inside the module body.
