These functions are useful to store and query driver private data a
After struct pwm_chip got its own struct device, this can make use of
dev_get_drvdata() and dev_set_drvdata() on that device.  These functions
are required already now to convert drivers to pwmchip_alloc() which
must happen before changing pwm_chip::dev.
