Fan: Allow fan count to be set dynamically
Currently, the fan count is statically set. This patch allows it to be set dynamically so that a single binary can support devices with a different number of fans (including fan-less). Signed-off-by: Daisuke Nojiri <dnojiri@chromium.org> BUG=b:116588924 BRANCH=none TEST=Boot Fizz with OEM=8. Verify fan spins with OEM=1.
