regulator: fixed: Add support to handle enable-active-high DT property
Add support to handle enable-active-high DT property. This property is used to drive the gpio controlling fixed regulator as active high when claiming gpio line. Signed-off-by: Vignesh R <vigneshr@ti.com> Acked-by: Simon Glass <sjg@chromium.org>
