ARM64: dts: rockchip: fixes the hw-tshut-polarity for rk3399

AFAIK, the hardware designed that TSHUT should be set the active high.

Since rk3399 evb designed the over-temperature protection pin is
connected to PMIC that active high vaild.
Also, as gru/kevin designed the over-temperature protection pin is
connected to EC control that active high to prevent leakage.
