sunxi: rsb: Enable R_PIO clock before configuring external pins
The original code was configuring the external pins after enabling
the R_PIO clock, which meant the configuration never made it to
the pin controller the first time in SPL.
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.
