If there is not currently any distinction that the kernel makes, you
only need to add "tcg,tpm-tis-i2c".

There are device trees that just have one or the other, so it makes
sense to list both.

IMHO could be picked to the same tree with DT changes instead

It's supposed to be the other way around. DT bindings go with drivers
via subsystem tree. I don't take drivers.
But it seems this first needs some coordination with this[1] series.
