[PATCH 43/47] pwm: renesas-tpu: Don't check the return code of pwmchip_remove()

["Uwe Kleine-König" <u.kleine-koenig@pengutronix.de>]

pwmchip_remove() returns always 0. Don't use the value to make it
possible to eventually change the function to return void. Also the
driver core ignores the return value of tpu_remove().
