Add support of sub-functions disabling. It allows one to define
an stmpe sub-function device in devicetree, but keep it disabled.

Hello,
the main reason for this patch is to allow enabling/disabling sub-fuctions
using DTS overlay to enable more flexibility on SoM/Carrier boards
combinations.

Hello Lee,
no problem, I thought it was that trivial to not create any worries.
I'll resend it in a while unless you take it before.

I like *all* patches to have a soak in -next.
You don't need to resend it. I'll apply it in due course.
