Maxim Semiconductor Max77620 supports alarm interrupts when
its die temperature crosses 120C and 140C. These threshold
temperatures are not configurable.
Add thermal driver to register PMIC die temperature as thermal
zone sensor and capture the die temperature warning interrupts
to notifying the client.

The previous question on compile test was more if we could add depends
on COMPILE_TEST flag. Sorry if I was not clear enough.
I am adding the flag here:

Support for die junction temperature
warning alarm for Maxim
but I still cannot compile test the file because of the missing header.
drivers/thermal/thermal-max77620.c:16:32: fatal error:

I wont be able to merge this as it is. We need to sort out the
dependency first.
I will update you once the mfd patches will merge as this header is on
that patch.
