As support for clk-measure expands across more SoCs, the current
approach of defining all SoC-specific clk-measure table data in the
driver .c file results in progressively larger compiled images,
resulting in memory wastage.

Move SoC-specific clk-measure tables to DTS definitions and extend
support for additional SoCs (A4, A5, S7, S7D and S6).

This breaks ABI and most importantly the clk measure feature on new kernel
and old DTs. So instead keep it as-is for current platforms and try to
add this for new platforms.

But the fact you need clkmsr-reg-v2 means you at least need to add a generic
compatible for v2 register map and drop this property.

Overall, I'm not a great fan of this, it moves data to DT and duplicates
the strings in _all_ board DTs, which is worse in fine.
