pwm: Drop duplicate check against chip->npwm in of_pwm_xlate_with_flags()
[ Upstream commit 91bb23493f8fd115e362d075ebaa3e6f12d1439d ]
args->args[0] is passed as parameter "index" to pwm_request_from_chip().
The latter function also checks for index >= npwm, so
of_pwm_xlate_with_flags() doesn't need to do that.
