usb: gadget: at91_udc: call at91udc_of_init only when needed
This avoids a build error in at91sam9261_9g10_defconfig:
drivers/usb/gadget/at91_udc.c: In function 'at91udc_probe':
drivers/usb/gadget/at91_udc.c:1685:34: warning: 'flags' may be used uninitialized in this
function [-Wmaybe-uninitialized]
board->vbus_active_low = (flags & OF_GPIO_ACTIVE_LOW) ? 1 : 0;
^
drivers/usb/gadget/at91_udc.c:1678:21: note: 'flags' was declared here
enum of_gpio_flags flags;
^
Making the call to at91udc_of_init conditinal also reduces
the object code size without sacrificing build coverage.
