usb: dwc3: keystone: drop dma_mask configuration
The Keystone 2 supports DT-boot only, as result dma_mask will be always configured properly from DT - of_platform_device_create_pdata()->of_dma_configure(). More over, dwc3-keystone.c can be built as module and in this case it's unsafe to assign local variable as dma_mask. Hence, remove dma_mask configuration code.
