[PATCH 17/17] arm64: dts: exynosautov9: add specific compatibles to several blocks

[Krzysztof Kozlowski]

ExynosAutov9 reuses several devices from older designs, thus historically
we kept the old (block's) compatible only.  This works fine and there is
no bug here, however guidelines expressed in
Documentation/devicetree/bindings/writing-bindings.rst state that:
1. Compatibles should be specific.
2. We should add new compatibles in case of bugs or features.

Add compatibles specific to ExynosAutov9 in front of all old-SoC-like
compatibles.  This will also help reviews of new code using existing
DTS as template.  No functional impact on Linux drivers behavior.
