arm64: dts: fsd: add specific compatibles for Tesla FSD

Tesla FSD is a derivative of Samsung Exynos SoC, thus just like the
others it reuses several devices from older designs. 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 Tesla FSD compatible specific to be used with an existing fallback.
This will also help reviews of new code using existing DTS as template.
No functional impact on Linux drivers behavior.

arm64: dts: fsd: Update cache properties

The DeviceTree Specification v0.3 specifies that the cache node
'compatible' and 'cache-level' properties are 'required'. Cf.
s3.8 Multi-level and Shared Cache Nodes
The 'cache-unified' property should be present if one of the
properties for unified cache is present ('cache-size', ...).

Update the Device Trees accordingly.

arm64: dts: fsd: drop useless 'dma-channels/requests' properties

The pl330 DMA controller provides number of DMA channels and requests
through its registers, so duplicating this information (with a chance of
mistakes) in DTS is pointless. Additionally the DTS used always wrong
property names which causes DT schema check failures - the bindings
documented 'dma-channels' and 'dma-requests' properties without leading
hash sign.
