Subject: [PATCH 1/3] dt-bindings: arm: stm32: Add compatible for syscon tamp node

Since commit ad440432d1f9 ("dt-bindings: mfd: Ensure 'syscon' has a
more specific compatible")
It is required to provide at least 2 compatibles string for syscon node.
This patch documents the new compatible for stm32 SoC to support
TAMP registers access.
