tg3: convert EEE handling to use linkmode bitmaps

Browse source 
Convert EEE handling to use linkmode bitmaps. This prepares for
removing the legacy bitmaps from struct ethtool_keee.
No functional change intended.

Note: The change to mii_eee_cap1_mod_linkmode_t(tp->eee.advertised, val)
in tg3_phy_autoneg_cfg() isn't completely obvious, but it doesn't change
the current functionality.
