Subject: [PATCH] arm64: dts: ti: k3-am62-main: Enable crypto accelerator

Add the node for sa3ul crypto accelerator.

Signed-off-by: Jayesh Choudhary <j-choudhary@...com>
---
On local testing, crypto self-tests and tcrypt tests were passing
for SHA256, SHA512, ECB-AES and CBC-AES algorithms.
RNG node has not been added due to the indirect access of the
hardware random number generator from OP-TEE.
