Subject: [PATCH 6.8 484/715] dt-bindings: arm-smmu: fix SM8[45]50 GPU SMMU if condition

From: Neil Armstrong <neil.armstrong@...aro.org>

[ Upstream commit dc94d0cc718329a39ea2e986a123421a9203b471 ]

The if condition for the SM8[45]50 GPU SMMU is too large,
add the other compatible strings to the condition to only
allow the clocks for the GPU SMMU nodes.
