pwm: atmel-tcb: Make private data variable naming consistent
Currently the variables of type struct atmel_tcb_pwm_device are named "tcbpwm", and variables of type atmel_tcb_pwm_chip are either named "tcbpwm" (too!) or "tcbpwmc". Rename the chips with device name to "tcbpwmc" to get a consistent naming.
