I don't think it makes sense to leak mode support into the legacy API.
The pwm_config() function is considered legacy and should eventually go
away. As such it doesn't make sense to integrate a new feature such as
PWM modes into it. All users of pwm_config() assume normal mode, and
that's what pwm_config() should provide.

Anyone that needs something other than normal mode should use the new
atomic PWM API.
