dt-bindings: thermal: Add Qualcomm MBG thermal monitor support

Browse source

Add bindings for the Qualcomm MBG (Master Bandgap) temperature alarm
peripheral found on the PM8775 PMIC. Unlike the existing SPMI temp alarm
peripheral, the MBG peripheral supports both hot and cold threshold
monitoring across two programmable levels (LVL1 and LVL2), with interrupt
status reported via a fault status register over SPMI.
