pwm: mtk-disp: Don't check the return code of pwmchip_remove()

[ Upstream commit 0f34b7a157a3c82a223c83c33bb6479df0bf8269 ]

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().
