[PATCH netdev-2.6#upstream] net: au1000_eth: PHY framework conversion

[Herbert Valerio Riedel <hvr@gnu.org>]

convert au1000_eth driver to use PHY framework and garbage collected
functions and identifiers that became unused/obsolete in the process

Signed-off-by: Herbert Valerio Riedel <hvr@gnu.org>
