pwm: atmel-tcb: Drop duplicated tracking of per-channel data
Per-channel data is tracked using struct pwm_device::chip_data and struct atmel_tcb_pwm_chip::pwms[]. Simplify by using the latter consistently. Signed-off-by: Uwe Kleine-König <u.kleine-koenig@pengutronix.de> Signed-off-by: Thierry Reding <thierry.reding@gmail.com>
