Gabe Black 1f4e283560 nyan: big: Only delay when and as long as necessary in the PMIC setup code. 
The PMIC setup code was unconditionally waiting for 10ms after each register
write. It might be possible for there to be an excess of current from lots of
rails switching around at the same time, but we can avoid that with a much
shorter delay in a few strategic places.

This change also moves the write to LDO3 to just under SD1 because LDO3 should
track SD1.

The duration and position for the delays and moving LDO3 were provided by Dan
Coggin at nvidia.

BUG=chrome-os-partner:25467
TEST=Built and booted on nyan rev1. Measured a 230 ms decrease in boot time.
BRANCH=None
