Subject: [PATCH 5.4 249/344] arm64: dts: ti: k3-j721e-main: Add missing power-domains for smmu

From: Lokesh Vutla <lokeshvutla@...com>

[ Upstream commit 3f03a58b25753843ce9e4511e9e246c51bd11011 ]

Add power-domains entry for smmu, so that the it is accessible as long
as the driver is active. Without this device shutdown is throwing the
below warning:
"[   44.736348] arm-smmu-v3 36600000.smmu: failed to clear cr0"
