We usually keep device nodes sorted by address, so this is out of order
and should come before i2c (at least). No need to respin just for this
though, I can fix it when I apply it, so:

Acked-by: Hector Martin <marcan at marcan.st>

Maintainers: as we usually ask, please merge only the driver commit (#2)
via the PWM tree, we'll take care of DTs/MAINTAINERS/bindings via
asahi-soc so we can avoid serializing/blocking other DT changes.
