[RESEND PATCH v4 2/2] arm64: dts: uniphier: add nodes of thermal monitor and thermal zone for LD20

[Kunihiko Hayashi]

Add nodes of thermal monitor and thermal zone for UniPhier LD20 SoC.
The thermal monitor node is included in sysctrl. Since the efuse might not
have a calibrated value of thermal monitor, this patch gives the default
value for LD20.
