Public TRM marks this region Reserved. Do you need it for anything?
This is copied from existing PRM data from kernel. However, I'll ditch
these for now and only retain the reset enabled domains.

Missing rstctrl and rstst offsets.
Will add.

No pwstctrl and pwstst bits documented in TRM or are marked reserved.
Same as coreaon.

All EVEs are missing rstctrl and rstst fields.
Will add.

Undocumented pwstctrl and pwstst registers.

Missing "device" and "instr" PRM. The latter doesn't have any pwrstctl
and pwrstst though.
Will ditch those.
