Description

Address and Data channels don't exist in the TL spec. There is a confusion as TileLink defines 5 channels called A, B, C, D and E. For TLUL version, only A and D are used, but A doesn't stand for Address and D is not for Data.

This will probably be a significant task as many (probably all) IPs are referring to these confusing words. Please also note that the `gen.py` and related scripts will also need to be changed.
