The ops are no longer device tree specific and are the generic ones provided by the core code. Convert the ops to the thermal_zone_device_ops format and use the new API to register the thermal zone with these generic ops. sata_ahci_read_temperature() is used by sata_ahci_show_temp() also. So in order to change the function prototype for the get_temp ops which does not take a void* but a thermal_zone_device* structure, this function wraps the call.
