Andre Przywara a08b318a15 pwm: sun4i: Propagate errors in .get_state() to the caller 
.get_state() can return an error indication now. Make use of it to
propagate an impossible prescaler encoding, should that have sneaked in
somehow.
Also check the return value of clk_get_rate(). That's unlikely to fail,
but we use that in two divide operations down in the code, so let's
avoid a divide-by-zero condition on the way.
