pwm: dwc: Make use of devm_pwmchip_alloc() function
This prepares the pwm-dwc driver to further changes of the pwm core
outlined in the commit introducing devm_pwmchip_alloc(). There is no
intended semantical change and the driver should behave as before.
Also convert the to_dwc_pwm() helper macro to a static inline to get
some type safety.
