[PATCH v2] USB: fsl_udc_core: use usb_endpoint_xfer_isoc to judge ISO XFER

[Peter Chen <peter.chen@freescale.com>]

Some ISO gadgets, like audio, has SYNC attribute as well as
USB_ENDPOINT_XFER_ISOC for their bmAttributes at ISO endpoint
descriptor. So, it needs to use usb_endpoint_xfer_isoc to judge
ISO XFER.
