[PATCH 02/22] soc: ti: k3-navss-ringacc: fix COMPILE_TEST link error

[Ahmad Fatoum <a.fatoum@pengutronix.de>]

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.
