[U-Boot] [PATCH fix for v2014.10] sunxi: axp152: dcdc3 scale is 50mV / step

[Hans de Goede]

Hi Tom,

Here is a last minute fix for v2014.10 to fix the axp152 code setting the
DRAM voltage way too high on some sunxi boards (2.3V instead of 1.5V).

I hope this can still make v2014.10, if not it is not too bad as most boards
use the axp209, not the axp152, and the axp152 boards I've seem to work fine
even with the 2.3V DRAM setting.

Regards,

Hans
