ppc: Create generic PPC driver framework.

This commit introduces a driver framework for power path controllers.
It provides some common PPC APIs as well as allowing a board to use
multiple different PPCs drivers/parts.  This should make it easier to
add PPC drivers in the future.

BUG=None
BRANCH=None
TEST=`make -j buildall`
TEST=Flash zoombini; verify PPC works as expected.
TEST=Flash meowth; verify PPC works as expected.
