The CPPI-4.1 driver selects TI_CPPI41, which is a dmaengine driver and that may not be available when CONFIG_DMADEVICES is not set:
warning: (USB_TI_CPPI41_DMA) selects TI_CPPI41 which has unmet direct dependencies (DMADEVICES && ARCH_OMAP)
This adds an extra dependency to avoid generating warnings in randconfig builds. Ideally we'd remove the 'select' statement, but that has the potential to break defconfig files.
