The ocelot_stats structures became redundant across all users. Replace
this redundancy with a static const struct. After doing this, several
definitions inside include/soc/mscc/ocelot.h no longer needed to be
shared. Patch 2 removes them.
Checkpatch throws an error for a complicated macro not in parentheses. I
understand the reason for OCELOT_COMMON_STATS was to allow expansion, but
interestingly this patch set is essentially reverting the ability for
expansion. I'm keeping the macro in this set, but am open to remove it,
since it doesn't _actually_ provide any immediate benefits anymore.

Ever since commit 4d1d157fb6a4 ("net: mscc: ocelot: share the common stat
definitions between all drivers") the stats_layout entry in ocelot and
felix drivers have become redundant. Remove the unnecessary code.

2.25.1
Ocelot uses regmap_bulk_read() operations to efficiently read stats
registers. Currently the implementation relies on the stats layout to be
ordered to be most efficient.
Issue a warning if any future implementations happen to break this pattern.

Since commit 4d1d157fb6a4 ("net: mscc: ocelot: share the common stat
definitions between all drivers") there is no longer a need to share the
stats structures to the world. Relocate these definitions to inside
ocelot_stats.c instead of a global include header.

Assertion holds even with my MAC Merge patch set that's in preparation,
so things are good.

There is a stray blank line at the end of ocelot_stats.c which this
patch adds and which doesn't belong. Either you keep this patch set
and fix it up later (I don't see another reason to resend except for
this), or you resend it. If maintainers don't complain about the new
line while the patch gets applied, I'm okay either way.
Anyway,

I think it's preferable to keep the moved code verbatim as-is instead
of additionally fixing the checkpatch warning in the same patch.
The mentioned cleanup could be a follow-up patch - togethar with the
trailing empty line removal.
