Hello Petri,

This looks good to me, some minor comments below

The last 4 bits contain the revision, although we never increased it, it
is safer to match with 0xffff_fff0. If that means dropping the catch all
40nm entry, that's fine by me.

Just use "Broadcom BCM7425" here, for consistency with the other
entries, and since that's really the internal PHY of the chip.

Same thing here.
