First of all, I'll note that changes like these need maintainer acks
before merging. Simple review for correctness is not enough!

While discussing this, there was perhaps a slight preference for moving
towards acronyms for brevity instead of expanding all of them to full
names. It can get a bit unwieldy.

For background, the reasons for having IS_<TLA>_DISPLAY_STEP() are
two-fold: the steppings used to be platform specific, so it made sense
to tie platform and stepping together, and IS_<LONG_NAME>_DISPLAY_STEP()
was considered too long combined.

Nowadays, we've abstracted steppings in code to be independent of
platforms, so we could use IS_<LONG_NAME>() && IS_DISPLAY_STEP(), and
throw out all the IS_<TLA>_DISPLAY_STEP() macros. They're orthogonal
things, and it actually bugs me to have so many platform specific
wrappers for the combos.

If in addition we moved to acronyms, we could have IS_<TLA>() &&
IS_DISPLAY_STEP(), and it would be pretty short and nice.

That said, all of these changes are a lot of churn, so I'd rather not
make them lightly.
