arm64: dts: mt8183-kukui: Add tboard thermal zones
Add tboard thermal zones.
The tboard thermal sensors are a kind of NTC sensors which are located
on PCB board to correlate the temperature of the case (Tskin).
pull-up voltage: 1800 mv
pull-up resistor: 75K
Vsense = pull-up voltage * Rntc / ( pull-up resistor + Rntc )
AuxIn = Vsense * 4096 / 1500
