This patch adds support for having a "fixed-link" to some other MAC
(like some embedded switch-device).
For this purpose we introduce a new phy-driver, called "Fixed PHY".
Fixed PHY works only with CONFIG_DM_ETH enabled, since the fixed-link is
described with a subnode below ethernet interface.
Most ethernet drivers (unfortunately not all are following same scheme
for searching/attaching phys) are calling "phy_connect(...)" for getting
a phy-device.
At this point we link in, we search here for a subnode called "fixed-
link", once found we start phy_device_create(...) with the special phy-
id PHY_FIXED_ID (0xa5a55a5a).
During init the "Fixed PHY" driver has registered with this id and now
gets probed, during probe we get all the details about fixed-link out of
dts, later on the phy reports this values.

The previous mv88e61xx driver was a driver for configuring the
switch, but did not integrate with the PHY/networking system, so
it could not be used as a PHY by U-boot. This is a complete
rework to support this device as a PHY.

Use the 'autoneg' flag available in phydev when checking if
autoneg is in use.
The previous implementation was checking directly in the PHY
if autoneg was supported. Some PHYs will report that autoneg
is supported, even when it is disabled. Thus it is not possible
to use that bit to determine if autoneg is currently in use or
not.

When configuring a PHY in fixed (forced) link mode, in order for
the changes to be applied, either one of these conditions must
be triggered:
1- PHY is reset
2- Autoneg is restarted
3- PHY transitions from power-down to power-up
Neither of these is currently done, so effectively the fixed link
configuration is not applied in the PHY.
Fix this by setting the Autoneg restart bit.

of_set_phy_supported allows overwiting hardware capabilities of
a phy with values from the devicetree. This does not work with
the genphy driver though because the genphys config_init function
will overwrite all values adjusted by of_set_phy_supported. Fix
this by initialising the genphy features in the phy_driver struct
and in config_init just limit the features to the ones the hardware
can actually support. The resulting features are a subset of the
devicetree specified features and the hardware features.

When a Gigabit PHY device is connected to a 10/100Mbits capable Ethernet
MAC, the driver will restrict the phydev->supported modes to mask off
Gigabit. If the Gigabit PHY comes out of reset with the Gigabit features
set by default in MII_CTRL1000, it will keep advertising these feature,
so by the time we call genphy_config_advert(), the condition on
phydev->supported having the Gigabit features on is false, and we do not
update MII_CTRL1000 with updated values, and we keep advertising Gigabit
features, eventually configuring the PHY for Gigabit whilst the Ethernet
MAC does not support that.
This patches fixes the problem by ensuring that the Gigabit feature bits
are always cleared in MII_CTRL1000, if the PHY happens to be a Gigabit
PHY, and then, if Gigabit features are supported, setting those and
updating MII_CTRL1000 accordingly.

Currently when phy device is created the link variable is
initialized to 1 which denoted phy link is already up. On a power
reset there is no issue as phy status register link status will
not be set, so phy auto negotiate will be started. But when a cpu
reset is issued (ex: dra72x-evm) phy's link status bit is already
set which leads to assume that link is already setup in
genphy_update_link() initial check which results in ehternet not
working. So do not assume that link is already up and on phy
device create set link to zero. This is verified on dra72x-evm.

de1d786 [add support for Xilinx 1000BASE-X phy (GTX)] introduced a
check for the extended status register in order to support
1Gbps-capable PHYs that don't have the 1000BASE-T registers. Since
Extended Status only indicates what the PHY (i.e. the local side) is
capable of, this broke communication with non-1Gbps peers.
Only check the extended status if the 1000BASE-T registers are
actually missing so we don't end up setting speed to 1Gbps even though
the previous test (for the combination of local and peer support for
1Gbps) already indicated we can't do 1Gbps with the current peer.

This reverts commit 041c542219.
The lines removed by this commit weren't redundant. The logic is (and

Find the intersection of the advertised capabilities of both sides of
the link (lpa).
From that intersection, find the highest capability we can run at
(that will be the negotiated link).
Now imagine that the intersection (lpa) is (LPA_100HALF | LPA_10FULL).
The code will now set phydev->speed to 100, and phydev->duplex to 1,
but this link does not support 100FULL.
