Merge branch 'net-dsa-cleanup-eee-part-2'

Russell King says:

====================
net: dsa: cleanup EEE (part 2)

This is part 2 of the DSA EEE cleanups, removing what has become dead
code as a result of the EEE management phylib now does.

Patch 1 removes the useless setting of tx_lpi parameters in the
ksz driver.

Patch 2 does the same for mt753x.

Patch 3 removes the DSA core code that calls the get_mac_eee() operation.
This needs to be done before removing the implementations because doing
otherwise would cause dsa_user_get_eee() to return -EOPNOTSUPP.

Patches 4..8 remove the trivial get_mac_eee() implementations from DSA
drivers.

Patch 9 finally removes the get_mac_eee() method from struct
dsa_switch_ops.
