Ah, I see now that you are moving securable peripherals into a new bus.
I share Uwe's confusion of considering the ETZPC as bus.

Does this configuration even change dynamically? Why can't you implement
this binding in the bootloader and have Linux only see a DT where unavailable
nodes are status = "disabled"; secure-status = "okay"?

For inspiration, see barebox' device tree fixups when devices are disabled
per fuse:

Ahmad
