I had made a mistake in updating the kernels and drawn a false conclusion.
The new result is:

all kernels I have tested between v6.10-rc1 and v6.11-rc6 report these messages.

But after 6.10-rc1 they appear to be harmless (I did not miss any functions so far)
and it is not clear if my 6.10-rc1 being stuck is related to this at all.

E.g. from 6.11-rc6:

root@letux:~# dmesg | fgrep 'device ID is greater than'
[    2.340148] ocp:target-module@48210000:mpu:fck: device ID is greater than 24
[    2.414978] ocp:target-module@54000000:pmu:fck: device ID is greater than 24
[    2.491973] 5a05a400.target-module:iva:fck: device ID is greater than 24
root@letux:~# 

BR,
Nikolaus
