Some ppc machines create a default usb controller based on a 'machine condition'. Until now the logic was: create the usb controller if: - the usb option was supplied in cli and value is true or - the usb option was absent and both set_defaults and the machine condition were true.
Modified the logic to: Create the usb controller if: - the machine condition is true and defaults are enabled or - the usb option is supplied and true. The main for this is to simplify the usb_enabled method.
