[RESEND PATCH v2] arm64: dts: Update cache properties for socionext

[Rob Herring]

From: Pierre Gondois <pierre.gondois@arm.com>

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.

I noticed this one fell thru the cracks from the rest of the series.

Arnd, Can you take this directly.

A bit after Pierre - in April 2023 - I sent similar which was said to be
"applied":
https://lore.kernel.org/all/f9a2c0d7-a78d-9368-f9bb-e8aba11e7d81@socionext.com/

Maybe the Socionext status in MAINTAINERS should be odd fixes?

Best regards,
Krzysztof

Sorry my mistake.
I thought Pierre's patch had been already applied, however,
I set Krzysztof's patch to "applied" but it was missing from the post to soc.

Since Krzysztof's patch includes the same "cache-level" lines as Pierre's,
the lines needs to be removed.

I'll post the update series including both to soc.

Thank you,
