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

Hi Maksim,

Apologies if I have failed to find a v7 of this patch in my searching, 
but I'm seeing that patch #3 here was never applied, so Linux still does 
not enable the thermal sensor in these chips. I just thought I'd give 
you a heads-up in case you weren't aware. :)

Thanks for all your hard work,
Sam

There is an unaddressed comment on this patch: to remove the "disabled"
status line. Sam, feel free to fix this and send the patch again,
unless Maksim beats you to it.

Cheers,
Andre

Any reason this is disabled? We typically don't disable those internal
devices in the SoC .dtsi, the THS is one example (check the instances
in other SoCs' .dtsi files).

The rest looks alright, compared to the manual, so with this line
removed:
