arm64: dts: exynosautov9: add specific compatibles to several blocks

Browse Source 
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.
