lm832x: Take DeviceState pointer in lm832x_key_event()
Since lm832x has been qdev'ified, its users will generally
have a DeviceState pointer rather than an i2c_slave pointer,
so adjust lm832x_key_event's prototype to suit.
This allows the n810 (its only user) to actually pass a correct
pointer to it rather than NULL. The effect is that we no longer
segfault when a key is pressed.
