soc/amd/picasso: Add generic SMU service request
Add a new feature that allows messages to be sent to the SMU. The
offsets of the PCI config index/data indirect registers have been
documented for prior generation devices.
The index/data pair is used to access a command register, a response,
and six argument values.
BUG=b:153264473
TEST=Verify service can be used to take the system into S3
