nyan: Set the CPU voltage differently depending on which PMIC is in use.
The PMIC used on the older pixel based nyan boards and the newer boards are
different and use a different base offset for their voltage settings. We need
to set them to different values in order to get the correct voltage out.
BUG=None
TEST=With this and other changes, built and booted on old and new nyan boards.
BRANCH=None
