pwm: Conflict with legacy PWM API
In order to avoid duplicate symbols with legacy PWM API implementations, the new PWM framework needs to conflict with any of the existing legacy implementations. This is done in two ways: for implementations provided by drivers, a conflict is added to the driver to ensure it will have to be ported to the PWM subsystem before it can coexist with other PWM providers. For architecture-specific code, the conflict is added to the PWM symbol to avoid confusion when a previously picked platform or machine can no longer be selected because of the PWM subsystem being included.
