Subject: [PATCH] riscv: dts: allwinner: d1: Add thermal sensor

From: Maxim Kiselev <bigunclemax@...il.com>

This patch adds a thermal sensor controller node for the D1/T113s.
Also it adds a THS calibration data cell to efuse node.

[John Watts: Remove disabled status]

This is a quick fixed version of Maxim Kiselev's patch from here:

https://lore.kernel.org/all/20231217210629.131486-4-bigunclemax@gmail.com/

It removes the disabled status as requested. I've tested it by adding thermal
zones to my board and it works from what I can see.
