Add suspend callback support for tsens which disables tsens interrupts

Would it not be preferrable to have the "critical overheat", wakeup-
capable interrupts be enabled, even if the system is suspended?

As part of suspend to RAM, tsens hardware will be turned off and it cannot generate any interrupt.Also system doesn't want to abort suspend to RAM due to tsens interrupts since system is already going into lowest power state. Hence disabling tsens interrupt during suspend to RAM callback.

Is that a hardware limitation, or a software design choice? I'm not
sure I want my phone to have thermal notifications disabled when
it's suspended.


As part of suspend to RAM , entire SOC will be off, this mode (suspend to RAM) is not intended for Mobile product. Tsens interrupts are not
disabled as part of suspend to idle(suspend mode for mobile).
