[PATCH 1/2] net: am65-cpsw-nuss: depends on DMA support

[Sascha Hauer]

The am65-cpsw-nuss needs DMA functions provided by CONFIG_DMADEVICES, so
we must depend on this option to avoid linker errors. As the am65-cpsw-nuss
is useless without the DMA hardware driver depend on CONFIG_TI_K3_UDMA
instead which implies CONFIG_DMADEVICES.
