The PSCI binding itself has provision for specifying function IDs for
different functions, and this seems to be followed by other subsystems
as well like SCMI:
https://www.spinics.net/lists/arm-kernel/msg791270.html
I could easily imagine that a firmware would provide two functions IDs
(one for AArch32, one for AArch64) and that it could change those over
time while not changing the compatible string at all.
