Merge branch 'cleanup-ocelot_stats-exposure'

Colin Foster says:

====================
cleanup ocelot_stats exposure

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.
