drm/radeon/dpm: disable cac setup on SI
Disable cac setup on SI for now since it causes
strange performance level restrictions on certain
cards. I suspect there may be issues with some of
the 64 bit fixed point double emulation that is used
to set up those parameters. I need to double check
the math before this can be re-enabled.
