[RFC v1 net-next 3/8] net: mscc: ocelot: expose stats layout definition to be used by other drivers

[Colin Foster]

The ocelot_stats_layout array is common between several different chips,
some of which can only be controlled externally. Export this structure so
it doesn't have to be duplicated in these other drivers.

Rename the structure as well, to follow the conventions of other shared
resources.

v1 from previous RFC:
    * Utilize OCELOT_COMMON_STATS
