usb: musb: USB_TI_CPPI41_DMA requires dmaengine support
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.
