pwm: Make pwmchip_[sg]et_drvdata() a wrapper around dev_set_drvdata() 

Now that a pwm_chip has a dedicated struct device, pwmchip_set_drvdata()
and pwmchip_get_drvdata() can be made thin wrappers around
dev_set_drvdata() and dev_get_drvdata() respectively and the previously
needed pointer can be dropped from struct pwm_chip.
