[net-next RFC PATCH 3/4] net: dsa: qca8k: rework mib autocast handling

[Christian Marangi <ansuelsmth@gmail.com>]

In preparation for code split, move the autocast mib function used to
receive mib data from eth packet in priv struct and use that in
get_ethtool_stats instead of referencing the function directly. This is
needed as the get_ethtool_stats function will be moved to a common file.
