Subject: [PATCH 02/11] habanalabs: set PM profile to auto only for goya

For Gaudi, the driver doesn't change the PM profile automatically due to
device-controlled PM capabilities. Therefore, set the PM profile to auto
only for Goya so the driver's code to automatically change the profile
won't run on Gaudi.
