pwm: mtk-disp: Don't check the return code of pwmchip_remove()
[ Upstream commit 9b7b5736ffd5da6f8f6329ebe5f1829cbcf8afae ]
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 mtk_disp_pwm_remove().
