Subject: [PATCH v4] arm64: defconfig: Enable TI PRUSS

The Programmable Realtime Unit - Industrial Communication Subsystem
(PRU-ICSS) known as PRUSS, is a low-latency microcontroller subsystem
used for industrial networking and other hard real-time functions in
the TI K3 SoCs such as AM654x, AM64x.

AM654x-EVM, AM64xx-EVM, and iot2050 use the PRUSS driver.
