[PATCH] w83781d: Document the alarm and beep bits

Document the individual alarm and beep bits of the w83781d driver.
Ideally we would offer a chip-independant interface for them, but
until it's done, it's only fair that we document the current
interface.

 If an alarm triggers, it will remain triggered until the hardware register
 is read at least once. This means that the cause for the alarm may
 already have disappeared! Note that in the current implementation, all
