pwm: renesas-tpu: Make use of devm_pwmchip_alloc() function
This prepares the pwm-renesas-tpu 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_tpu_device() helper macro to a static inline to get
some type safety.
