thermal/drivers/rcar_gen3_thermal: Create device local ops struct

Browse Source 
The callback operations are modified on a driver global level. If one
device tree description do not define interrupts, the set_trips()
operation was disabled globally for all users of the driver.

Fix this by creating a device local copy of the operations structure and
modify the copy depending on what the device can do.
