Separate common fan behavior from implementation
This looks like a lot, but it's really just moving the non-board-specific
stuff from chip/lm4/fan.c into common/fan.c, updating the appropriate
headers, and renaming functions to better match the new location.
This is entirely code refactoring and renaming. No new functionality.
BUG=chrome-os-partner:23530
BRANCH=none
TEST=manual
make runtests, build all platforms, build and test on Link.
