Change subject: superio/fintek: Add f81803A ......................................................................
superio/fintek: Add f81803A
Add f81803A plus the capability to control the fan with any fintek SIO. This will be done through a common API, though currently only F81803A will have it implemented.
BUG=none. TEST=Tested later with padmelon board.
