This chip is present on Apple M1 (t8103) platforms:

* atlantisb (apple,j274): Mac mini (M1, 2020)
* honshu    (apple,j293): MacBook Pro (13-inch, M1, 2020)
* shikoku   (apple,j313): MacBook Air (M1, 2020)
* capri     (apple,j456): iMac (24-inch, 4x USB-C, M1, 2020)
* santorini (apple,j457): iMac (24-inch, 2x USB-C, M1, 2020)

Hector says that it was mentioned in the prior review round as well.
It's the revision ID. The mask allows all IDs for chips where no
split has been seen, but if a new one comes up that comment is there
so we know where to split the mask.

Alright, makes sense. If you happen to re-spin the series then it would
be nice to include this info in the commit message.

And maybe even change the comment to something like:
