hw/input: Remove lm832x device

Remove the lm832x keyboard-and-pwm i2c device model. This
was only used by the n800 and n810 machines.

(Although this is an i2c device and so in theory available to create
on the command line, in practice it has an outbound IRQ line that the
machine model needs to wire up, and the only way to inject keys events
into it is to call the lm832x_key_event() function, so it isn't
in practice possible to use it separately from the n800/n810.)
