[PATCH v2 2/4] usb: gadget: atmel: Code refactor part 2

[Zixun LI]

- Rename atmel_usba_start() / atmel_usba_stop() to usba_udc_enable()
  / usba_udc_disable(), remove atmel_ prefix to be inline with other
  functions. Also avoid confusion with DM start() / stop() functions.
- Replace printf() by log_err()
- Spelling paramter -> parameter
