Add initial support for a XFI backplane interface on some new platforms.
The XFI backplane requires a custom tuned link. Hardware/Firmware owns
the link config for XF backplane and software must not interfere.

This patch updates the configuration of PHY from Inphi (www.inphi.com)
to flush the register write with a reg read.
The Inphi PHY is configured in ixgbe_setup_mac_link_sfp_x550a.
The Inphi PHY setup flow has been updated to read configuration reg,
write only linear/non-linear, and then read (write flush).

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.

This patch removes the flow control conversion from Rx and Tx to pause
and asymmetric pause, as that is handled by the ixgbe_negotiate_fc().
Performing the conversion prior to ixgbe_negotiate_fc() results in
an incorrect fc mode if Rx only pause is selected when the link partner
is advertising Tx.
