You should set up the supplies to point to whatever regulator is
supplying the power. If there are supplies on the board which are
generated using fixed voltage regulators then you should register those
using the fixed regulator driver. Recent kernels are more tolerant of
missing supplies but it's still better to be explicit if you can be.
