Subject: [PATCH v3] arm64: dts: ls1088a: add one more thermal zone node

Ls1088a has 2 thermal sensors, core cluster and SoC platform. Core cluster
sensor is used to monitor the temperature of core and SoC platform is for
platform. The current dts only support the first sensor.
This patch adds the second sensor node to dts to enable it.

Signed-off-by: Yuantian Tang <andy.tang@....com>
---
v3:
	- use more descriptive name for each zone
v2:
	- Add more information about sensors to description
PS: In order to keep consistency to the first thermal-zone node, there will
be "WARNING: line over 80 characters" warnings.
