If you can add an index and add the index definition in devicetree
header file, it will be more convenient when binding power domain to
device in DT file. such as
[ZX296718_PM_VDE] = &vde_domain.dm,

> + &hde_domain.dm,

Suggest to rename probe function and of_device_id to a generic zx
name, then add compatible data so that probe function can be shared.
Probe function can find SoC specific data via comparing compatible
string and initialize device accordingly.
