Add nvmem-cells to describe chip information like chipvariant and
chipspeed. If nvmem-cells are used, the syscon property is not necessary
anymore.

Done now, although it is not aligned with DTS in this patchset, so this
does not look tested...

Best regards,

I will wait for them to be fixed then.

NAK

And unreviewed. Please carry on:

Nacked-by: Krzysztof Kozlowski <krzysztof.kozlowski@linaro.org>

I found older discussion with Rob, who pointed out that one device
cannot have entirely different programming models, so this patchset has
the same errors. None of the previous issues were fixed here.

Best regards,
Krzysztof
