pwm: sifive: Don't check the return code of pwmchip_remove()
[ Upstream commit ceb2c2842f3664dcc4e6d8cb317e1e83bb81b1e5 ]
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 pwm_sifive_remove().
