Right now there are no users of aw88261 in the kernel device tree sources.
This patch is part of an effort to mainline the FairPhone 5, for which we 
will add the first use of this compatible, and there we need to specify 
dvdd-supply for this chip's power supply.

Since there are no present users, I thought it was OK to add a new required 
property. If not, I can make it optional.
