Hmm. Thermal sensor IP with no interrupt? Looks really strange.

This is odd, because LVTS always has multiple interrupts, and if this doesn't
actually feature any, it really feels like the hardware is broken somehow.

MediaTek, can you please confirm whether the LVTS IP in MT7987 is really
like that, or can you please give the right interrupt number to Frank?

Thanks,
Angelo
