Why this was working before is uncertain. Maybe the state was left from a previous boot sequence, or RSB just happened to be the default configuration. However with some A33 chips, SPL failed to configure the PMIC. This was seen by me and Maxime on the Sinlinx SinA33 dev board. Reordering the calls fixed this.
