arm64: dts: mt8183-kukui: Update Tboard sensor mapping table 



According to auxadc change the readback value from raw data to Vsense.
Update the tboard table that temperature map to Vsense.

pull-up voltage: 1800 mv
pull-up resistor: 75K

Vsense = pull-up voltage * Rntc / ( pull-up resistor + Rntc )
