This patch adds Energy Efficient Ethernet (EEE) support for
some Marvell PHYs on some future platforms.
Because EEE capability or status was not indicated previously,
this patch simply assumes that it is supported.
As soon as there is a PHY that does not support EEE, there will
be defects in this area because the driver will not report the
EEE status correctly.
This also deletes some now-unused definitions from an earlier
Marvell PHY implementation and combines a device ID check into a
switch statement.

Create flow control (FC) setup and enable functions to configure PHY
registers. These registers advertise FC settings according to the user
requested mode. On link establishment, these settings are negotiated
with the link partner to agree on the settings to use: RX and TX enabled,
TX only enabled, or FC disabled and RX enabled (which also enables TX).
Remove the part of code that performs FC auto-negotiation (AN) in
ixgbe_setup_m88 and put it in a new function to maintain consistency
with other FC AN implementations so far. Add function pointers to the
setup-fc and enable-fc functions so that they get called during init
