Subject: [PATCH net-next 2/3] net: dpaa2: convert to use .get_rx_ring_count

Convert the dpaa2 driver to use the new .get_rx_ring_count
ethtool operation instead of implementing .get_rxnfc for handling
ETHTOOL_GRXRINGS command. This simplifies the code by removing the
ETHTOOL_GRXRINGS case from the switch statement and replacing it with
a direct return of the queue count.

The driver still maintains .get_rxnfc for other commands including
ETHTOOL_GRXCLSRLCNT, ETHTOOL_GRXCLSRULE, and ETHTOOL_GRXCLSRLALL.
