Disable runtime power management on several sienna cichlid
cards, otherwise SMU will possibly fail to be resumed from
runtime suspend. Will drop this after a clean solution between
kernel driver and SMU FW is available.

[Quan, Evan] Better to move this to sienna_cichlid_check_bxco_support(). As long as smu_baco->platform_support is set as false there,
the runpm will be disabled accordingly I think.
Either way the patch is reviewed-by: Evan Quan <evan.quan@amd.com>

Good point. We probably want to disable BACO entirely or enable the
workaround because BACO could also be used for a GPU reset in some
cases. Then only disable runtime pm if BACO will be used. BOCO
should still work fine for example.

As far as I remember, the WA proposal still wants to retain BACO as a
