thermal/drivers/mmio: Switch to new of API 



The thermal OF code has a new API allowing to migrate the OF
initialization to a simpler approach. 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.
