axgbe: Various link stability and module compatibilty improvements

Move the phy_stop() routine to if_detach() to prevent link interruptions
when configuring the interface. Accompanying this is a sanity check
using phy_started, which was already there but remained unused. We do
not move phy_start(), as the logic there is needed for any init routine,
be it attach or start.

Also bring in the linux PMA_PLL change which addresses the flapping of
back-to-back fiber connections.

Use miibus for SFP PHYs up to 1G copper. We retry in cases where the PHY
is not directly reachable. Set the correct IFM_100_SGMII flag when the
phy speed has been set to 100. We remove xgbe_phy_start_aneg() since
it's handled by miibus.

Add support for 100 and 1000 BASE-BX fiber modules

Add support for 25G multirate DACs which are capable of 10G.

While here, also fixup the LINK_ERR state. It was impossible to recover
from this previously.

[[ Note: light style fixes by imp, slight commit message adjustment,
and a warning that I don't have the hardware to validate, but
the changes do track the commit message and seem otherwise OK ]]

10Gigabit Ethernet driver for AMD SoC

This patch has the driver for 10Gigabit Ethernet controller in AMD
SoC. This driver is written compatible to the Iflib framework. The
existing driver is for the old version of hardware. The submitted
driver here is for the recent versions of the hardware where the Ethernet
controller is PCI-E based.
