this m-labs/migen#292 should be merged in migen before, so it wont raise a TypeError, when oe1 and oe2 are a _Slice

Thanks @maass-hamburg for looking at this. We are currently not using upstream migen due to change to pyproject.toml for the installation so would also need to fix this if m-labs/migen#292 is merged to use it.

@enjoy-digital and what exactly is the problem with the pyproject.toml in migen?
We need that fix also for #2060 so we can use the DDRTristate when oe1 and oe2 are of the type _Slice. It being that, would be the most common way to use it wenn it is use for something with multiplie lanes, like in LIteSPI.

@enjoy-digital the part that needs m-labs/migen#292 and #2073 is now separated into #2074

the difference is that: 46be90e

@enjoy-digital you might want to take another look. This now don't require the change in migen.
