Right now the driver doesn't support any interrupts, but it may support
in future. The "alert-therm2" is a maskable interrupt and the "therm-
addr" can't be masked and is "always enabled" into the chip.

I didn't use "minItems: 1" because I wanted to leave to the user the
decision if he needs any interrupts into their system
