Supplies should only be optional if they may be physically absent from
the system, if they are just sometimes not described well in firmware
they should be requested via the normal regulator_get() interface, the
core will supply a dummy regulator if there is nothing at all in the
firmware description.
Supplies should also generally be referred to with the naming used in
the datasheet for the part.
