There was probably also a problem as I did not unload intel_atomisp2_pm. 
That is what lsmod reports now:

$ lsmod | grep atom
atomisp               790528  0
videobuf_vmalloc       16384  1 atomisp
videobuf_core          28672  2 atomisp,videobuf_vmalloc
punit_atom_debug       16384  0
snd_soc_sst_atom_hifi2_platform   110592  2 snd_intel_sst_core

mc                     53248  3 atomisp,videodev,atomisp_ov2680

But it looks as there are no devices for atomisp, or ov2680:

pgfeller@ASUS:~$ ls -l /sys/dev/block | grep atom
pgfeller@ASUS:~$ ls -l /sys/dev/block | grep 2680
pgfeller@ASUS:~$ ls -l /sys/dev/char | grep atom
pgfeller@ASUS:~$ ls -l /sys/dev/char | grep 2680
