Description
We are vendoring in Ibex into OT, and we need to avoid files being duplicated, or core files in Ibex overriding ones in OT.
General rules:
- If code from OT is needed, it *must be* vendored in.
- If code is not vendored in, it *may not* use the same `name` in the core file, and ideally also not the same file names.
One example we know of right now is the mem_model at https://github.com/lowRISC/ibex/tree/master/dv/uvm/core_ibex/common/mem_model; there might be others.
This issue is to double-check all core files, and to ensure that the rules outlined hold.

Research direction
Start by inspecting dv/uvm/core_ibex/common/mem_model and compare it with the corresponding vendored-in OpenTitan code. Then review the other core files against the stated naming and vendoring rules; done means non-vendored OpenTitan code is not duplicated or able to override Ibex code.
