The TI UDMA driver has a fixed dependency on the K3 RINGACC driver,
which is not necessarily satisfied during COMPILE_TEST as the latter
depends on ARCH_K3 being enabled, which is an ARM-only symbol
unavailable when compile testing on other architectures.
Fix this by selecting the code as needed.

Enable support for the TI UDMA (Unified DMA) controller. This
DMA engine is used in AM65x and j721e.
