ARM: pxa: remove broken balloon3_gpio_vbus reference
ARM: pxa: remove broken balloon3_gpio_vbus reference

balloon3_udc_init() tries to register a balloon3_gpio_vbus
device, but this has never been defined in the mainline
kernel. To avoid the obvious build failure when this function
is enabled, remove the bogus reference here.
