ixgbe: E610: add discovering EEE capability

Add detecting and parsing EEE device capability.

Recently EEE functionality support has been introduced to E610 FW.
Currently ixgbe driver has no possibility to detect whether NVM
loaded on given adapter supports EEE.

There's dedicated device capability element reflecting FW support
for given EEE link speed.
