requesting driver will always try to enable/disable regulator as

The reason for that is that we didn't actually look at the real

hint and started to relocate based on self calculated data from

To ensure we're not running into such a situation again, this patch

trust the phys/virt hints from the payload. We also should check that
we really only have a single section, as the code doesn't handle
