Subject: [PATCH] pwm: Add missing dummy for devm_pwmchip_add()

The PWM subsystem supports compile-testing if CONFIG_PWM is disabled.
However, no dummy is provided for devm_pwmchip_add(), which may lead to
build failures.

Fixes: bcda91bf86c1ff76 ("pwm: Add a device-managed function to add PWM chips")
