[PATCH u-boot-marvell 04/19] net: mvneta: Remember fixed link instead of PHY address in priv data

["Marek Behún" <kabel@kernel.org>]

From: Marek Behún <marek.behun@nic.cz>

We don't need to remember PHY address anymore, because since using DM
MDIO for connecting PHY, the address is parsed by mdio-uclass from
the ofnode.

But the driver uses a special value of the address to signal fixed link
usage.

Drop phyaddr add fixed_link in driver private structure. This simplifies
code a little.
