Just move this to the parent and make the parent a pwm provider. There's
no need for child nodes for this or the rtc.

hmm, there are apparently devices without rtc. If there is a child node
for the rtc, the corresponding devicetrees could disable rtc by not
having that node.
But maybe using the controller version is also feasible for that task.

If not probeable, then the compatible string should distinguish that.

Okay.

It's even simpler in some cases: The firmware version reported by the EC
should tell us if it's one that is known to have no RTC.

That said, I don't have a good overview of the different variants of
this device.
