ar8216: add 802.3az EEE info to swconfig get_link attribute
AR8327/AR8337 allow to read the result of EEE autonegotiation.
If EEE is autonegotiated between the link partners, display
this as part of the swconfig get_link attribute.
eee100: 100MBit EEE supported by both link partners
eee1000: 1GBit EEE supported by both link partners
