thermal: max77620: Add thermal driver for reporting junction temp
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.
