This code runs only once, so it is not worth the effort IMHO.

If I would introduce a table to store the revision of the IRQ core, I would have
to put a value into that for each different SoC. That means 15 entries at the
moment.

Alternatively I can introduce a global variable to store the revision, and
intialize that variable from the SoC detection code. However I would have to set
that variable individually for each SoC and that means 15 lines of code.

Yep, will fix it.
