dm: power: Add a function to set up all regulators
The device tree provides information about which regulators should be on at boot, or always on. Use this to set them up automatically. Signed-off-by: Simon Glass <sjg@chromium.org> Tested-by: Przemyslaw Marczak <p.marczak@samsung.com> Acked-by: Przemyslaw Marczak <p.marczak@samsung.com>
