[PATCH v1 1/1] dt-bindings: cache: bt1-l2-ctl: Remove soon be unused bindings

[Andy Shevchenko]

As stated in [1] the Baikal platforms are not supported and
the respective driver code is going to be removed. Remove
soon be unused bindings.

This feels like it should have been in a series with the driver removal.
If Krzysztof wants to take it with the driver to avoid warnings in his
tree:

Otherwise I'll revisit this in a day or two and grab it.

Cheers,

Yeah, he pointed out to the DT submitting patches documentation, so now
it's clearer.

Thanks!

It will be a v3 of the combined patches in a series.
