Subject: [PATCH 4/7] arm64: dts: ti: k3-am64-main: Add eQEP nodes

Add eQEP DT nodes 0-2 for AM642 SoC.

Since external hardware was needed to test eQEP, the DT nodes
for eQEP were not included in the introductory commit. Now that
eQEP has been validated, add nodes to k3-am64-main.dtsi.

Fixes: 8abae9389bdb ("arm64: dts: ti: Add support for AM642 SoC")
Signed-off-by: Judith Mendez <jm@...com>
