net: stmmac: convert to use .get_rx_ring_count

Browse Source 
Convert the stmmac driver to use the new .get_rx_ring_count
ethtool operation instead of implementing .get_rxnfc for handling
ETHTOOL_GRXRINGS command.

Since stmmac_get_rxnfc() only handled ETHTOOL_GRXRINGS (returning
-EOPNOTSUPP for all other commands), remove it entirely and replace
it with the simpler stmmac_get_rx_ring_count() callback.
