i2c: Adapter timeout is in jiffies
i2c_adapter.timeout is in jiffies. Fix all drivers which thought
otherwise. It didn't really matter as long as the value was only used
inside the driver, but soon i2c-core will use it too so it must have
the proper unit.
Note: for the i2c-mpc driver, this fixes a bug in polling mode.
Timeout would trigger after 1 jiffy, which is most probably not what
the author wanted.
