No, there are two problems here.
1. the the _PSD warning, this is because the buggy acpi tables exported by BIOS
2. cpu p-state not working, this is because that the HARDWARE address space is
used for p-state control on a non-Intel processor, which is not supported.

Q1 is a BIOS issue,
and Q2, it's also not a software problem.
We don't know why the HARDWARE address space is exported and don't know if it
works, unfortunately we don't have any AMD guys here to consult.
Venki, do you have any thought?
