ath79: use upstream properties to disable EEE

The hack-patch which introduced the "at803x-disable-smarteee" for
disabling SmartEEE did in fact not disable SmartEEE but rather disabled
802.3az "standard" EEE.

This can be done by using the upstream properties "eee-broken-100tx" and
"eee-broken-1000t". EEE is then disabled by the PHY subsystem.

Tested on devolo WiFi pro 1200e.
