On newer SoCs, the PWM can require a power-domain to operate so add it
as optional.

If required, then how is it optional?

If the 'newer SoCs' means the one you just added, then this should be 
squashed into the prior patch with a conditional schema making it 
required for the new compatible.

Newly adding SoC's PWM definitely requires power-domains, older SoCs
don't have dedicated power-domain for that that kind of periphery.
But I can't say other new SoCs won't require it too that's why I made it
by a separate patch. And squash the power-domians patch into main one
is ok too.
