In Linux, a pwm_chip can have more one pwm_device, one for each channel.
Therefore, pwm_apply takes a pwm_device as argument to identify, which
channel is the one being operated on.
In barebox, there's a 1:1 relationship between the two, but let's add
pwm_device as extra, so far unused, parameter to make porting kernel
code slightly easier.
