dt-bindings: thermal: rcar-gen3-thermal: Add r8a779h0 support

Document support for the Thermal Sensor/Chip Internal Voltage
Monitor/Core Voltage Monitor (THS/CIVM/CVM) on the Renesas R-Car V4M
(R8A779H0) SoC.

Just like on other R-Car Gen4 SoCs, interrupts are not routed to the
INTC-AP (GIC) but to the Error Control Module (ECM).
