pwm: vt8500: Rename variable pointing to driver private data
Status quo is that variables of type struct vt8500_chip * are named "vt8500", "chip". Because usually only struct pwm_device * variables are named "pwm" and "chip" is usually used for variabled of type struct pwm_chip *. So consistently use the same and non-conflicting name "vt8500".
